[cobirds] Bird Conservancy of the Rockies - Barr Banding Report 8/31/23

Well, we weren't "hopping" like Chico, but we did feel like the Wilson migration began today. We captured 10 new ones, including our first adult (out of a total this season of 23).  To compare this with last year, which was a good year in terms of numbers, by this time we had captured 109 WIWAs (9 of which were adults).  Lots of thoughts about why.......

Twenty-three new birds today:

Dusky Flycatcher 1 (first of season)

Willow Flycatcher 1 (FOS)

Red-breasted Nuthatch 2

House Wren 1

Orange-crowned Warbler 1

Yellow Warbler 4

American Redstart 1(FOS)

Common Yellowthroat 1

Wilson's Warbler 10

Chipping Sparrow 1

If you would like to visit, we have one-hour slots (up to 15 visitors at a time) from 7:30-8:30 most weekday mornings (Tues-Fri, we are closed on Mon) and 8, 9 , and 10 a.m. one-hour time slots on the weekends.  Click here to make a reservation.

Re: [cobirds] Red Crossbills & sunflowers

As far as recording sounds from the phone, here is what I do, if that helps.

I personally use either Merlin or SongSleuth apps on my phone for bird sound recording.  SongSleuth was intended to work like Merlin before there was Merlin, but it is pretty terrible at sound ID.  However, it does make good quality sound recordings - at least on par with Merlin, and maybe a little better at picking up some things.

I then email the sound file to myself using the little sideways open triangle icon located somewhere near the file.  Then I go do the rest from a computer instead of the phone.

There are a lot of .wav file trimmer tools available for free, and some are simpler than others.  I think the last one I used was called Clideo.  Perhaps others can recommend the fastest, simplest online .wav file trimmer they've used?   

From my email I download the sound file to my desktop and then use the .wav file trimmer to cut it down to the desired area and save it with a new name back on my desktop (which preserves the original in case I want to trim down to some other section as well).  

Finally, I upload the trimmed file to my eBird checklist the same way photos are uploaded there.

I hope that helps someone!

My take is that, yes, it appears to have been a productive year for certain types of red crossbills.  Yes, juveniles seem to hang together.  Yes, perhaps their straight, barely curved, and/or newly crossed bills might make sunflower seed from flowers easier to obtain than conifer seed.  Yes, all the rain down low this year grew a TREMENDOUS crop of sunflowers.  Yes, still lots to observe, learn, and report.  I think I am hearing two types of red crossbills in urban Fort Collins (2s for sure, and maybe 4s?), both getting sunflower seed from flowers.  I know, I know, record them, edit the giant resultant files, create sonograms, get confirmation of the types.  I wish I knew how, which is nobody's fault but my own.  Just haven't paused to figure it all out for my clunky phone. Please tell me, which paper cup has the record button, or is it on the string?

 

The next "The Hungry Bird" article in the upcoming fall issue of "Colorado Birds" happens to be about what crossbills eat other than conifer seed.  Of course, the article was "in the can" before all this flurry of sunflower seed-eating we are witnessing.  The article gives this specific issue only minor mention.  Such is the nature of our business.  We should regret having only partial knowledge and revel in the opportunity to grow it.

 

Thanks for everyone who has shared their red crossbill sunflower experiences at feeders or at flowers.

Subject: Re: [cobirds] Red Crossbills & sunflowers

 

In general, if breeding is successful in significant increases in the population and cone crops are small or depleted, Red Crossbills will erupt beyond usual ranges or habitats and pursue atypical food sources.  Red Crossbills tend to wander wherever the food is to be found and so may have less site fidelity than some other species.  I suspect the crossbills in the Boulder area had a successful breeding season and have well-enjoyed the local cone crops and now are dispersing due to their increased numbers to take advantage of a wider variety of foods. It has been noted that immature birds sometimes go through a teenager phase where they hang out together more than with the mature birds.  But the details about bill development and specific food sources is interesting!

Thanks, Dave, for the report about the crossbills in Fort Collins.

 

Your post got me wondering:

 

1. If juvenile crossbills are still developing curved beaks, might that explain why we don't see adults in these flocks feeding on sunflowers?  Could the juvenile beaks be more suited to prying seeds from the sunflowers than prying them from pine cones?  Or might adult beaks be less suited to sunflowers? (Although many of the juvies I saw yesterday had less curved beaks, several had very curved beaks, so maybe this theory doesn't work.)

 

2. Is there a shortage of food in the foothills for the juveniles?  There have long been sunflowers on the plains, but this is the first time I've seen crossbills encamped at the Community Gardens.  (They're still there, as of 6:45 this morning.)

 

3. Do juvenile crossbills generally separate from the adults and form juvenile flocks?

 

Here's a shot of one of the juvies yesterday.

Re: [cobirds] Red Crossbills & sunflowers

Regarding the Red Crossbills eating Sunflower seeds, my friend Lynda Ryan shared this on social media, as well. She witnessed young Red Crossbills feeding on Sunflower seeds at Rock Ledge Ranch in Colorado Springs. She was also very surprised. Here is a picture she took. 

Lynda is not part of this group, so I asked her permission to share this with you all.

Richard Trinker just reported to eBird an observation of juvenile red crossbills at low elevation eating sunflower seed obtained from flowers at a public garden in Boulder. I had the same exact experience yesterday in two different yards on the east side of Fort Collins. The individuals I watched were young enough to have mostly straight beaks. Their vocalizations were a better way to quickly discern their not being house finches than their general appearance.  Juveniles have also been at Grandview Cemetery in Fort Collins recently.  It has been suggested this might indicate local, urban breeding. However, Richard's and the Fort Collins observations suggest to me a widespread Front Range  shift of young birds to low elevation of unknown duration to take advantage of an abundant, easy to obtain nutrition source.

The next issue of "Colorado Birds" has a "The Hungry Bird" article on crossbills foods OTHER THAN conifer seed but I didn't say much about sunflower seed and juveniles because the literature doesn't address it and I hadn't personally seen it before yesterday.

[cobirds] DFO Sept Program: Magnificent Eleven Owls of Northern Colorado, by Scott Rashid

Join us to watch the Magnificent Eleven Owls of Northern Colorado, by Scott Rashid.
Monday, Sept. 18, 7 p.m. MDT
Webinar via Zoom (We will post registration information here as soon as available, or you can visit https://dfobirds.org and check out Upcoming Programs)

Whooo knew? . . . that 11 of the 19 species of owl found in the US occur in northern Colorado? Who else but Scott Rashid, that's hooo. The veteran Colorado owl researcher, bander and rehabilitator will tell us all about them at the September DFO monthly program.

Those Magnificent Eleven owl species: Barn, Boreal, Burrowing, Eastern Screech, Flammulated, Great Horned, Long-eared, Northern Saw-whet, Northern Pygmy, Short-eared, and Snowy. Rashid may know them better than anyone in the state, having worked with owls here for more than 30 years. Besides his field research, Rashid has been illustrating and writing about birds for nearly 35 years.

[cobirds] Bird Conservancy of the Rockies - Barr Banding Report 8/30/23

Even warmer than yesterday and continued slow.

The birds of note today were the three Red-winged Blackbirds, all in the middle of body, wing and tail molt.  Like the Grackles we caught earlier this week, RWBLs are rare captures at the station (these were the first since 2016), probably having something to do with the higher water levels later in the summer than usual.  Here's today's 15 new birds:

Mourning Dove 1

House Wren 5

Yellow Warbler 1 new, 1 banded last year

Wilson's Warbler 3

Yellow-breasted Chat 1

Red-winged Blackbird 3

If you would like to visit, we have one-hour slots (up to 15 visitors at a time) from 7:30-8:30 most weekday mornings (Tues-Fri, we are closed on Mon) and 8, 9 , and 10 a.m. one-hour time slots on the weekends.  Click here to make a reservation.  (For folks who tried to use the link from yesterday to register, my apologies - try again, as this one should work!)
