[cobirds] Evening Hummer study at Ken Caryl, JeffCo Friday evening 7/29

CoBirders and lovers of hummers,

Here is a short, evening DFO field trip to my yard to study hummers:


I have nice hummer activity at my feeders now, and evening is a very pleasant time for viewing and for decent numbers (about 25 hummers are here this evening). We will expect Broad-tailed and Rufous, and hope for Calliope and Black-chinned. We'll look for good opportunities to study individuals and I'll walk us through the ID points. Lighting should be good for pictures, too. Registration and details are here. 

DFO trips are free and open to all.

[cobirds] Yellow Rail Update Wed

My daughter has wanted to hear them so we have been out there 3 times now. Here  are the results:

Monday eve 7:00 pm:  Slight rains. Only click click was the patter of rain on the hat. No birds.
Tuesday eve 7:00 pm:  Slight breeze, overcast, no birds
Wed Morning 5:30 to 6:30 am: Overcast but no winds or rains. Took a while to hear the first...near the west barricade and about 100 feet west of there. This is a little farther west than usual. Daughter was happy to hear it loud and clear. The bird near the parking lot was silent for most of the hour...only finally vocalizing in the last 5 minutes.

[cobirds] Cassia Crossbills continue at Rock Creek Trail

Our DFO field trip was successful in enjoying the Cassia Crossbills at Rock Creek Trail, and even more Type 2 Red Crossbills. We didn't have other types of Red, or White-winged, either. In our experience today the crossbills were active and calling a lot until 9:30 am, and were much less evident after that. Today was sunny and pleasant. I'm glad we were at the trail by 7:40 am.

I include a recording that has both Type 2 Red Crossbill and Cassia Crossbills. The latter begin calling at 36 sec. into the recording when a small group flew in, their lower 'chut' calls mingling with sharper 'kip' of the Reds.. And a pic of one of our Cassia's by participant Ginny Bergstrom.

We encountered about 20 Cassia at 0.3-0.4 mile up the Rock Creek Trail, and then we had at least 9 more Cassia as singles or small groups from 0.5-0.8 mile. They responded well to my Nor. Pygmy-Owl imitation, and that seemed to draw in the first group we had. I think we also had Cassia at the main trailhead parking lot, and further down at two places as we drove up, but we were unable to document these. Type 2 Reds were more numerous for us on the Rock Creek Trail, with at least 46 noted. There were numerous juveniles of both species, esp. among the Type 2 Reds.

[cobirds] Bands on Cassia Crossbills

Cobirders,

It's my understanding that quite a lot of Cassia Crossbills have been banded in Idaho over the years.  The ratio of the fraction of banded Cassia to banded Red must be enormous.  If you see crossbills in CO, please take a special look out for leg bands, as it's possible that that could help determine whether the CO Cassias have dispersed from southern ID.

Re: [cobirds] Re: Important notes on Cassia Crossbill and Merlin

If you go into explore birds you can adjust the filter to a specific location. 

I have not found a wat to turn off location.

Hi Norm (and other android users),

I managed to get my Android phone to figure out the Cassia Crossbill calls I recorded yesterday near Silverthorne. In my recordings, I selected 1 of them that I thought had the Cassia in it (originally Merlin only identified Red Crossbill) and then tapped the Edit button on the top right. Then I selected Change Location >, then selected the Choose... option. Then I entered Albion, ID in the Search by City or Zip.. and when it returned that location, I selected it. Merlin then re-evaluated my recording and identified Cassia Crossbill in addition to Red Crossbill.

So, if you are looking for the Cassia's in the next few days, record everything in Merlin, then try this when you get home. It might work out in the field too if you have cell service, but I don't know for certain.

Hope that helps folks.

[cobirds] CASSIA CROSSBILLS-Yes

COBirders,

Several of us just heard, recorded & photographed at least 2 CASSIA CROSSBILLS at Eric DeFonso's location downhill of the 2 trail junction. Still calling as I type this.

Recordings were also made of a possible White-winged Crossbill with a (maybe) photograph.

[cobirds] Orchard Oriole, Pueblo County, 7/25

Good morning,
  I found an adult male Orchard Oriole on the DOT Road yesterday, north of Pueblo Airport, where the road bends east to cross Chico Creek.  It was in the riparian bushes along the creek and was pretty skulky.  No other birds of much note, though there were remarkably large numbers of American Kestrels along IL Road, parallel to the DOTR on the east side of the Pueblo Depot Activity - I counted 14 in the five miles or so of that road.

Re: [cobirds] LBHE at RM Arsenal (Not)

That is the bird I saw as well; south Lake Ladora, yesterday. I am going through all of my photos to find the best ones. I took my sighting down until I process my photos.

Our bird had the gray leg color into the feet (not yellow) and did not appear to have the yellow lores like Bill's (not visible from this photo). Will report back if someone in the group has a better photo, but sharing a shoddy iPhone/Scope pic for now.

The pale yellow lores were suspect. Its foraging behavior is similar to the other SNEG as is its general posture. Another photo (which I posted on eBird) that I was able to take today shows a distinct color change from green legs to yellow green feet, something I missed the day before. Also the leading edge of the legs show clear traces of black, which is something mentioned in Sibley for the juvenile SNEG. See the pic! (It was as if it knew what I came back to look for:)

[cobirds] Yellow Rail news from Randy Vernon

Randy Vernon contacted me this morning from Monte Vista NWR to tell me he was able to view one of the singing adult Yellow Rails through a gap in the reeds this morning, at the original parking pullout that Eric DeFonso described. He also heard the second rail singing near the tree further west. He then proceeded east to the next pullout by the pond and heard a third rail singing near the west edge of the pond. No documentation though. If anyone finds any additional singing birds, please try to document these rare birds by recording audio.

Thanks,

Re: [cobirds] LBHE at RM Arsenal (Not)

Well darn, I'll have to examine my photos closely. I thought it was a LBHE, and not a SNEG.  Hopefully I got some photos of the feet. But the one I saw didn't appear to have the yellow lores that yours have in the photo. I'll know more when I put my pictures on my computer screen.

Re: [cobirds] CASSIA CROSSBILLS continue in summit county.

Hello all,

Here are a few more details on our encounters with apparent Cassia Crossbills in Summit County today. The first encounter was a quick flyover by a few birds right near the junction between Summit County Road 1851 and 1850 (i.e. the left turn signed to Rock Creek Trailhead). The exact spot was: https://goo.gl/maps/24CazNVzuQG5bAxw7, but it's probably best to park in the large pullout at the road junction just a little farther west.

Here's a link to the checklist with my recording of those birds:

We stopped a few other places along Rock Creek Road but did not have any more Cassia Crossbills until we reached the spot where Eric DeFonso reported them. To reach this spot, take the left turn onto Rock Creek Road (CR 1350), go all the way to the trailhead at the end, and then hike about half a mile up the trail to the first trail junction (link to map: https://goo.gl/maps/AjiqSdNPq3mRkMM16). Just as Eric reported, several crossbill family groups were foraging in this area, sometimes quietly, sometimes noisily coming and going. The majority were Type 2, with a few apparent Cassia Crossbills mixed in.

I made several recordings of the crossbills at this second location, which can be accessed here:

Be aware that the family groups of crossbills included many begging juveniles, singing adult males, and chitter calls from feeding flocks, in addition to flight calls and excitement calls, so the sounds coming from these birds are numerous and varied. Most of the crossbills in the area are Type 2, with apparent Cassias making up perhaps 20% or so. One group of Type 5s flew over us along the road.

Best of luck to anyone who chooses to chase these birds -- and remember to make audio recordings!

[cobirds] Grand County-Green Mountain Trail

My husband and I hiked in Grand County earlier this week, including in an area burned by the 2020 East Troublesome Fire north of Grand Lake, and thought we would share a few observations of birds, plants, and our impressions of the area 21 months post-fire.  We hiked the Green Mountain Trail to Big Meadows, a beautiful 2 mile trail we have hiked from time to time over the last three decades.  The trail recently re-opened after it was cleared and log bridges were replaced, etc.  All of the trees in this area burned. Some trunks are still standing; many lay on the ground; many burned to ash. 

The wetter areas and some hillsides were incredibly lush with grasses and wildflowers including fireweed, thistle [primarily Cirsium centaureae I think), bedstraw, arnica, lupine, cow parsnip, harebell, yarrow, monkshood, asters/daisies and others.  And somewhat surprising to me, there were more bird species than I expected to see or hear.  Lincoln's Sparrows were singing in many of the grassy drainage areas. We saw or heard Pine Siskins sparsely throughout; we saw one picking at one of the thistles.  A few Mountain Bluebirds flew through the burned tree trunks.  I sat in the grasses at the edge of Big Meadows for about 15 minutes to take it all in and recorded several species of birds – Western Wood-Pewee, Broad-tailed Hummingbird, American Robin, Mountain Chickadee, Pine Siskin, Yellow-rumped Warbler, and Lincoln's Sparrow – even though the trees ringing the large meadow were all burned.  I reported 11 bird species total for our hike. https://ebird.org/checklist/S115398835

This forest area will be very different, but aspens are already coming up in the previous aspen areas.  It will be most interesting to see how this area transforms from burned soil, wood, and ash over the next three decades. Thanks to Jack Bushong's Grand County article a few weeks ago, publicized by Mark Obmascik's Cobirds post. We added a few more ebird lists for Grand County.

Re: [cobirds] Potential CASSIA CROSSBILL in SUMMIT COUNTY

Hi everyone,

By sheer luck and coincidence, I happened to be in almost the same area as Luke and Will but a couple days earlier, on July 17. Specifically I was walking along the Rock Creek trail in the Eaglesnest Wilderness (where the Alfred M Bailey Bird Nesting Area is) when I came across a group of crossbills feeding on some dead but cone-rich lodgepole pines close to the trail. I've been seeking to record crossbills any chance I get, although that is admittedly not an easy task, as they are either often not close, or not cooperative. But this time, they were, at least enough so. As I was recording, Merlin surprisingly boldly flashed "Cassia Crossbill" as their identity after hearing the call notes. I was naturally a bit skeptical, although I was also feverishly wanting Merlin to be right.

After seeing Luke and Will's message this morning (I finally returned from my field season last evening), I was reminded and encouraged to inquire about whether I too had encountered Cassia Crossbills, given that I was as close to their location as I was, in space and time. Around midday today Matthew Young at Cornell confirmed that my recordings were entirely those of Cassia Crossbill.

My recordings can be heard here in the checklist:

[cobirds] Climate Change

Hi

If you are concerned about climate change, think about trees. Just one healthy tree can absorb from the air a whopping 50 pounds of noxious, climate-changing, carbon dioxide in just one year! One large tree can supply a healthy dose of oxygen to sustain four people for one day.

The next time you see a tree, stand in front of it and graciously bow, then take one step forward and with great passion give the tree a big meaningful hug, then happily move on.

Live nest cam on a House Finch nest that was built over my front door.  It was a Robin nest in the spring and the Finches moved in after the Robins fledged.  Various videos and a link to the live feed are on this web page:   http://nest.dandietrich.com/
They will probably be fledging in a few days.

MONITORING FOR YELLOW RAIL IN COLORADO WITH ERIC DEFONSO
 Friday, July 22, 2022 5:00PM—7:00PM

Description: Earlier this week Eric DeFonso discovered a singing yellow rail only the second ever for Colorado (first was in 1906). Later a second one was found in the same marsh. CFO will offer this field trip to educate birders about this interesting bird.

We will journey to the Monte Vista NWR to listen carefully for the extremely rare Yellow Rail that has been detected since July 12th. The bird can be heard from the auto-tour route at the 2nd stop (about 2/3 mile from the main entrance), but we will also listen for a 2nd bird that has been reported between the 1st and 2nd stops. We will arrive in the late afternoon (after 5pm) and leave when Refuge closes to the public 1 hr after sunset (9:22pm, or 2122), or earlier if participants are ready to do so. The Yellow Rail is only detectable by its characteristic ticking sound – the bird has not yet been seen, nor is likely to be seen. Photography is unlikely, but please feel free to bring cameras and especially your means of recording bird sounds! Cell phones can make pretty good recordings these days, and that's what I used when recording the bird back on the 12th when I first encountered it.

Eric DeFonso has been involved in the birding and conservation community in Colorado for over 15 years, ranging from volunteer stints with a raptor rehabilitation program and being on the Board of Directors for the Fort Collins Audubon Society, to giving presentations to Audubon chapters across the state and guiding field trips for the Colorado Field Ornithologists. Eric has an extensive collection of bird sound recordings, and now writes a regular column on birding by ear for the journal Colorado Birds. Eric has also been a surveyor for the ongoing IMBCR Breeding Bird survey project run by the Bird Conservancy of the Rockies since 2013, and has been the crew leader since 2021. He also now serves on the Colorado Bird Records Committee, and edits reports for the North American Birds journal by the American Birding Association (ABA).

[cobirds] white ibis, Riverbend Ponds, Fort Collins

Last Tuesday, Dilka Murtazina found and photographed a white ibis at Riverbend Ponds in Fort Collins. To my knowledge, no one else was able to get on this bird in spite of diligent searching until this morning, when Mike and Libby Edwards relocated the bird in the same spot Dilka had originally found it. It was still present just after 2PM today, at the following location:
https://www.google.com/maps/place/40%C2%B034'21.4%22N+105%C2%B001'45.2%22W/@40.572611,-105.029212,17z/data=!3m1!4b1!4m5!3m4!1s0x0:0x7b949191bab8b42!8m2!3d40.572611!4d-105.029212

The map will make it look as if the site is in the northwest lobe of one giant pond, but the water is now shallow enough to make the site a separate pond.

Riverbend Ponds has three parking areas: north parking area off Timberline Road, south parking area off Prospect Road, and northeast parking area off Cherly Street. Prospect might be the most convenient. From there, head north and west until the river stops you, and turn north. Hope it sticks around!
