[cobirds] Northern Parula, City Park, Denver

After commitments in Denver this afternoon, I stopped by City Park for a while. Among the many Yellow-rumps I found a Northern Parula just northwest of the gazebo at the west end of Ferril Lake. Other storm-blown birds in the park included Mountain Bluebirds, a Vesper Sparrow, and hundreds of swallows (of only three species, oddly).

[cobirds] Re: A Beginners' Guide to Swallow ID.

The issue of swallow ID has been understated for decades as far as books and articles go. Sure, gulls, shorebirds, seabirds are traditionally among the tougher families for US birders. Well Empids, sparrows, fall warblers, etc etc as well.

USA swallows are highly mobile and visible species, more limited in diversity than the above listed groups, and limited enough that swallow ID should not be a huge issue. But it is.

As an "experienced" birder, until the day by a lakeside in north Texas, in peak swallow migration, that I realized that swallows were not as easy peasy as I always thought.  Peak swallow-migration time, standing at the shore of a large reservoir near Dallas, with hundreds of swallows of various species, and less than ideal lighting from the birder's vantage point.   Surely swallow ID is easy, but when you have hundreds/thousands of birds zipping and darting and swooping around in front of you, it is QUITE difficult to ID bird-by-bird what you're looking at. When you're in an area where every swallow (besides Violet-green, in this Texas example) is perfectly expected and usual, it is quite hard to gauge a ratio of which species to species mix you're looking at in a migratory flock over a lake in poor viewing conditions. And swallows love to congregate and feed over lakes.

Thank you Joe Roller for the swallow-ID post.  It is not an easy task to come across giant mixed migrating flocks of swallows and determine how many of each species you're looking at, or even rough ratios.  More work should be done on this front.

Good birding,

[cobirds] Migrants, Clear Spring Ranch, El Paso Co, Sat.

Hi COBirders,

I decided to take a chance on the cold, snow, ice, and mud this morning and try some banding at CSR. Things were definitely moving!

I banded an Audubon's Warbler (SY Male), and 3 Orange-crowned Warblers, saw several more, and several "bounce-offs" by Myrtle Yellow-rumped Warblers. Also banded were some White-crowned, and Lincoln's Sparrows, a Spotted Towhee, and a couple Am Goldfinch males.

In addition, there was a giant flock of mixed RW Blackbirds and cowbirds, and at least one Yellow-headed Blackbird male. These were working the freshly plowed field, then up to the cottonwood tops to feed on catkins. Also 10 Franklins Gulls, and dozens of mixed sparrows worked through the edge of my area. Then the wind kicked up again, and I closed the nets.

After a slow week with wind and wet, maybe the migratory floodgates are ready to break.

Happy Migration,
Steve Brown

[cobirds] Sanderling - Highline Lake SP - Mesa County


 
This morning I had a Sanderling at Mack Mesa Reservoir feeding along the shoreline with 13 American Avocets and 2 Willet's.  There was also a flock of 20 Eared Grebes in the middle of Mack Mesa Reservoir, which is located in Highline Lake SP.

I believe the Sanderling to be an adult female.  The only rufous I could see was a hint along the primaries near the tail - everything else was black, gray and pure white.

[cobirds] Summit County Birds

Hi all, 
Today I was up in Summit County and was able to do some birding. At Bills Ranch Lake there were many Cassin's Finch, Red Crossbill, Pine and Evening Grosbeaks, as well as a Fox Sparrow in a clump of willows nearby. There was an American Kestrel and Northern Goshawk on the lake as well. At Dillion Reservoir in the Blue River Inlet there were numerous American Pipits and a pair of American Dippers constructing a nest. At the Snake River Treatment Plant there was a Vesper Sparrow, and a possible Eastern Bluebird. Near Frisco Marina there was a Semipalmated Plover alongside two Least Sandpipers, as well as a Peregrine Falcon, Northern Shoveler, and 5 Willets! 



Good birding,

[cobirds] Orange-crowned Warbler and other snow birds, Estes Park, Larimer Co.

Continuing our spring (though it seems like winter up here) visit to Estes Park, on my morning walk today in the snow I found a first-of-year Orange-crowned Warbler on the west end of Estes Park. No other eBird reports yet for this year up here. I also encountered a large flock of Ruby-crowned Kinglets feeding together in a couple of ponderosa pine. Numbers of Myrtle and Audubon's Yellow-rumped Warblers are increasing even with the snow. This being my first visit in April, I've been surprised at the numbers of Myrtle Warblers I've seen. Here in Estes Park, and a few days ago in Colorado Springs, they seemed to outnumber the Audubon's Warblers that I observed. It would be interesting if eBird did a dynamic map showing the migration of each form to see if Myrtle moves through somewhat ahead of Audubon's which will stay to breed here in the foothills and mountains.


I had a large flock of what I believe were American Pipit fly over me headed toward Rocky Mountain National Park. I didn't find any eBird reports for Pipit up here yet for this year. Flocks of Red-winged Blackbirds and Common Grackles seemed to be staging this morning, presumably waiting for the snow to clear so they can move on up to breeding areas.



Always something interesting to discover in the world of birds.

[cobirds] Yesterday in Weld

Greetings All

Yesterday, Nick Moore and I birded Weld County, starting at Crow Valley and finishing at Union Reservoir.
The fallout was impressive, if not more for bird numbers than rarity.

We had 125 species in all.
The rarest birds were a Western Palm Warbler at the Eaton Cemetery and a Glossy Ibis (injured, not with other ibis) near Lower Latham.

Crow Valley was packed with Spotted Towhees (and a Spotted x Eastern), Lincoln's Sparrows, and OC Warblers. A White-throated Sparrow was singing away incessantly and two early Gray Catbirds scurried in front of us amongst the towhees.

It looks as if a PB Grebe may be attempting breeding just n. of the campground area.  

Bushtits are still hanging around various clumps of conifers near the pond at Glenmere, which had about 6 BC Night Herons and a Snowy Egret -- the neighborhoods were stuffed with OC and YR Warblers.

A late Lesser Black-backed Gull (near adult) remains at Union.

Good Birding

[cobirds] A Beginners' Guide to Swallow ID.

Birders,
There is often great info on CObirds about sorting out rare and tough, look-alike bird species.

But for many less-experienced members of our field class fraternity and the scope sorority,
this weekend is a great time to learn to identify Swallows in Flight. 

At almost any water body there should be swallows, put down by the nasty weather,
which keeps insect morsels "down on the deck." (see footnote).

This weekend, swallows in flight will be close and near eye level, thus easier on your neck 
than when you gaze at stratospheric dots on clear days.
Swallows on a wire are easier. Just like in the field guides.

Get your warm clothes, anorak, hot tea, big hat, gloves, and a buddy and get thee to a lake! 
Park close, using your car as a blind and look, look, look.

Here is how I sort out swallows on gray days, when colors are muted and visibility is iffy.

Look at the swallows closest to you first, especially ones that are moving toward you. They will be moving fast
and hard to keep in view, but be patient, trying to stay on ONE swallow until it gets way too far away. Take a stab at an ID,
then find ONE more.

Here are the six most common birds in the swallow tribe, in pairs of two, roughly in order of prevalence.

First, look for a swallow that seems all dark. That will be your Barn Swallow. In gray conditions don't bother looking for colors - the dark blue back
and orange breast - or for the forked tail, which can be hard to see, as those are only confirmatory field marks.

Cliff Swallows are easy, with the orange rump. But on dark overcast, the rumps may appear just pale & contrasty, not bright orange.
"Cliff's" confirmatory mark is the BROAD squared off tail. Other swallows have square tails, but appear much narrower.

Next, find one that seems dark above, white below.
These will be either Tree or Violent-green Swallows. 

To sort out those two can be tough, but the VG's will give a flash of its bright WHITE "Saddle-bags".
Trees lack that or may have just a hint of white on the sides of the rump. IF you see Violet on a Violet-green,
come back on a darker day!

The other good mark for those two is the large white cheek of the VG. Trees have a little white on the lower cheek, but not much.

If you are not sure whether it's a Tree or VG, it's probably a Tree, as VG's stand out and are hard to mistake for a tree.

Next are the brownish backed pair -  Rough-winged and Bank. Banks rare among the swallows you'll see, so don't expect too many. 
Maybe below 1%.

Rough-wings have pale bellies, but NOT bright white like Tree and VG.
If you have a candidate for Rough Winged or Bank, look at the throat. Rough wings have a dull brownish throat.

And don't look for the brown breast band on Banks. That's a good mark for a perched Bank, 
but in flight, look for the White CHIN. It stands out because it's bordered by the brownish head
 and the brown breast band, but the white chin stands out. You may not find any on a given lake.
And Bank Swallows could have been included in a trio of the other two WHITE-bellied swallows.

There are a ton of other field marks, size, tail shape, sluggish or sprightly flight, etc, but the field marks I mentioned are the place to start.

As for Cave Swallows and Purple Martin, you won't see any this weekend. 

If you get a chance to test these tips in the field, please let me know which ones are the most or the least 
helpful for you. Constructive comments are welcome.

My next topic will be a beginners' guide to distinguishing a hawk from a handsaw.

Joe Roller
Denver


footnote:
The classic question non-birders ask is, "What's up with all the swallows at intersections?"   The best theory I have heard is that cars idle there, 
so intersections are warmer than any one street. The warmth and carbon dioxide from car fumes attract bugs. Microclimate.

[cobirds] Worm-eating Warbler, Boulder

Hi all,

I found a Worm-eating Warbler this morning along Boulder Creek below the CU Rec Center.  It was near the west end, south of the creek, just east of the pump station (there is no longer a footbridge across the creek at the pump station, so you'll have to cross the creek closer to Folsom and walk west).  It was seen right around the bench commemorating Ruth Leinbach, and around the adjacent small flooded hollow.  Given the weather forecast, I imagine it will probably stick around.

[cobirds] Important reason for maintaining records

Hi
As well as the excellent reasons already given for maintaining a state record committees, it is also important to maintain zoological collections in museums particularly with the advent of DNA technology where determining species relationships requires physical information. So institutional record keeping is critical, otherwise we wouldn't know what resource to look up to see what that bird is we are looking at.

[cobirds] RBA

Hi All-

I'm filling in for Joyce temporarily and just found out I need to start tonight.  

Given its migration, CFO Convention time, etc.,  I am going to remove old sightings quicker than Joyce does.  If I remove a sighting that should remain as the bird is still being seen — PLEASE contact me and I can add relevant info.

PLEASE do not be offended if I do not credit everyone who found the bird and just note the last source I  am aware of whom has most information wrt relocating the bird.  E.g., birds seen at CFO Convention will be found and seen by "CFO Convention birders found XXXX at XXXX"


CFO Convention participants and other birders can help during this busy time for birders if you contact me: TEXT (303)888-5110 or e-mail (ahilf@me.com<mailto:ahilf@me.com>) any updated daily RBA info. that is not reported via COBIRDS.

I am cleaning out the last RBA info to make room for all the goodies that are visiting Colorado. Hope everyone is out looking for additions to tomorrows RBA.

Thanks, and I apologize for the lack of the RBA the past two days — it will return shortly,

[cobirds] Corrected: Cancellation of May 1, DFO trip to Jackson Lake State Park

Hey all, 
It appears that the email I just sent to Cobirds didn't come out right so I am re-posting this.

Due to weather,

​ we are cancelling the Sunday trip to Jackson Lake State Park.

 

 

​We
 have been watching the weather forecast closely and have determined for everyone's safety and health, we should cancel the trip.  The winds will make the cold temps even more miserable
​ and​
roads will be slick from all the moisture this week.  We will certainly try and set it up again later in the summer.  

The weather forecast for Ft. Morgan is as follows: 

Saturday Night

A 30 percent chance of snow, mainly before midnight. Cloudy, with a low around 33. Breezy, with a north wind 9 to 17 mph, with gusts as high as 26 mph. New snow accumulation of less than a half inch possible.

Sunday

chances of rain and snow before noon, then a slight chance of rain. Cloudy, with a high near 46. North wind 8 to 10 mph becoming east northeast in the afternoon. Winds could gust as high as 16 mph. Chance of precipitation is 20%.

 

 

Thank You

Mark,

 

You answered your own question by reminding birders about the Baikal Teal behind the Baskin Robbins.  It was a "real" bird but it was found during a period when Baikal Teal in their natural Asian range were in severe decline after having been the most common duck in its range.  Also, anyone can currently buy a pair of Baikal Teal for a farm pond for $400.  The ornithological record is way more than a birder's eBird claims. It is a method of documentation that describes in writing for perpetuity what the bird was doing, what it looked like, where and when it was seen, and why it wasn't a look-alike species. eBird reviewers and eBird users make mistakes.  Rare bird committee members make mistakes too, but there 7 people evaluate a record, ask experts from outside of CO when needed, vs. the one eBird reviewer.  If you want Baikal Teal on your personal list, tick it, but there were excellent ornithological reasons not to have it become part of the official CO bird list.  Careful documentation, especially when a suite of photos or sound recordings are included, adds very valuable ornithological information for Colorado. eBird, IMO, not so much.

 

Respectfully,

In an age of Ebird, CObirds, and even Facebook bird ID groups, why do Colorado and other states still have state bird record committees?

 

After John Ealy found the hooded oriole in his Douglas County backyard, many excellent birders asked to have documentation submitted to the Colorado Bird Records Committee, which decides whether rare-bird reports are legitimate. I submitted, but the process is a hassle. The website crashed, and instructions weren't always clear.

 

I know this an all-volunteer effort, and money is short, and I'm always in favor of something that increases interest in and knowledge about birds, but what does the committee do that isn't already being done elsewhere in a more convenient way? In my experience, Ebird reviewers do an excellent job of screening entries. (They've found a bunch of my mistakes.) Ebird and CObirds make it easy to add photos. And with its international reach, Facebook allows fast access to ID experts whose yardbirds are our vagrants.

 

It's also tough for me to forget how the committee decided that Bill Brockner's Baikal teal, seen by me and hundreds others behind the Baskin Robbins in Evergreen a few years back, was not actually a real Baikal teal. 

 

If there's a good reason to keep submitting to bird records committees, I'd like to hear it.

 

Good birding.

Re: [cobirds] State Bird Records Committee

These pasted from the Colorado Bird Records Committee page <http://coloradobirdrecords.org/> offer some response to the question:

"The primary purpose is to provide a repository for information regarding the records of rare or unusual birds within the state of Colorado. In order to perform this function, the CBRC solicits, collects, assembles, reviews, renders opinions on, and permanently archives, in the Denver Museum of Nature and Science, all documentation concerning rare and unusual bird records in Colorado."

And

"Birding anecdotes are great fun, but like any oral history, they disappear over time. By providing details of rare bird sightings in an archival documentation, birders contribute to a collective body of knowledge that spans generations.  The intent of the Colorado Bird Records Committee's peer review process is NOT to validate an individual's sighting or personal list, rather it is to establish a standard for which rare bird reports can be used as scientific-quality data."

Re: [cobirds] State Bird Records Committee

Mark,
I understand your concerns, but Bird Record Committees have NOT been surpassed by eBird,
and I am a huge supporter of e Bird. e Bird species ID reviewers do great work, but each of them is staunchly
supportive of the CBRC.

Perhaps the current chair of the Colorado Bird Record Committee, Mark Peterson or 
the recent chair, Doug Faulkner, now President of CFO, can take the time to answer your questions
point by point.

In the meantime, I will just say that detailed documentation of any rarity and many more common birds
is absolutely necessary for Colorado to have a "clean" state list, unimpeachable.
Norm Erthal found Colorado's first state record of Hooded Oriole, and he and I (who was with him) prepared
detailed reports to the CBRC, even though there were fine photos. Yes, it was sort of a hassle, but well worth the effort.
I yearn to send the CBRC detailed reports of the next Colorado Wood Stork, Olive Warbler and other birds that require 
documentation. Those would be happy hassles.

And to second guess the 7 or so highly expert committee members' decision about the Baikal Teal is not reasonable. As I recall, the bird
was thought to be a "real female Baikal Teal," but it's "provenance" was the sticking point. Many more Baikal Teal
are kept in aviaries in the US than are thought to have flown here from Lake Baikal.  And there was an aviary 
a short distance from Evergreen. That is just the way I recall it, perhaps not exactly correct. Ditto with the 
Evergreen Rufous-collared Sparrow. Species ID was not questioned, but they are good singers, are
widely kept as cage birds and are not vagrants to the US.

Mark, I'd be glad to chat with you on the phone, as space here is limited. There are marked differences
between e Bird reviews and CRBC reviews. Just look at the issue of Colorado Birds that describes 
the tremendous effort the CBRC did in analyzing the ID of Colorado's only Kelp Gull and it's "wild"
provenance.

Re: [cobirds] State Bird Records Committee

Mark and Cobirds:

I will share the primary reason I believe that Bird Records Committees (BRCs) are important.  They are repositories for bird records.  A one-stop shop.  Yes, one can submit photos to eBird, Cobirds, and any number of other online sites, but availability to that information is not long-lived.  A BRC acts like a museum.  The records submitted to it are available for easy, public consumption in perpetuity.  Yes, there is the vetting process that BRCs perform for what constitutes a "record", and that is important, but to me it is the repository aspect that makes BRCs necessary.

One could argue that museums are no longer necessary because collecting is not performed at the same level as in the past.  Yet, they provide a valuable resource to researchers because of their repositories of specimens.  In much the same way, BRCs provide a repository of bird records that can be used by researchers now and 100 years from now.  Try finding any information about the Hooded Oriole on the internet next year, 5 years from now, or in 50 years.  Instant gratification and information sharing is great, but it is fleeting.  BRCs are in it for the long-haul.

respectfully,

Doug Faulkner

[cobirds] Yuma County mini fallout, 4/28/16

Folks,

I encountered a mini fallout in Yuma County yesterday on my way home from work in Nebraska. If it had only been one or two weeks later, I'm convinced it would have been massive. As it was, it was still a little early. Still, it was a very, very good day in Northeast CO in April.

Some of my highlights included:

Three Harris's Sparrows,a White-throated sparrow, and a Red-bellied woodpecker in Laird on the Nebraska border

Among the dozens of Yellow-rumped Warblers and Orange-crowned Warblers dripping from the trees in Wray, I had a Prothonotary Warbler, a Yellow Warbler, and three Common Yellowthroats, all of which got themselves flagged in eBird. Somewhat surprisingly, a Least Flycatcher did not. Chimney Swifts have arrived in town.

More warblers at Stalker Lake. There were warblers in the sagebrush, warblers in the trees, and warblers on the ground. At one point, I was looking at 3 'Western' Palm Warblers, all perched on or underneath the same picnic table. Nearly every sparrow I looked at was a Clay-colored, though I did have a few Chipping, a singing Brewer's, and a singing Field Sparrow. The lake was covered swallows; I was actually surprised I didn't see a Purple Martin, but I did have the five other expected species (no Violet-green). Shorebirds included Baird's, Least, Semipalmated, Spotted and Solitary Sandpipers, and also 4 Willets, 32 Long-billed Dowitchers, Greater and Lesser Yellowlegs, and 1 Wilson's Phalarope. I flushed an American Bittern, which headed upstream, and also flushed an early Green Heron, which sat in a tree for a photo.



Terrible photo, but that's the best I could do with an iPhone and a pair of binoculars. At least it's in focus.

Beecher Island hosted a number of good birds as well, such as Northern Bobwhite, Osprey, Eastern Screech-Owl, Red-bellied Woodpecker, Eastern Phoebe, Eastern Bluebird, Northern Parula, another Harris's Sparrow, and another White-throated Sparrow

102 total species in roughly a half-day of birding. There seemed to be birds in every tree. Here's hoping this weather produces some more great birds this weekend
