[cobirds] Magnolia Warbler, Walden/Sawhill Ponds, Boulder County
While out today we came across a gorgeous male Magnolia Warbler in the Sawhill Ponds portion of the area. Coordinates: 40.0422995, -105.1961588 We also ran into Cara Stiles about 15 minutes after she had seen the Golden-winged Warbler but we were unable to refind that bird at the time. We did find the larger flock of Yellow-rumped Warblers but they were moving back and forth along the creek on both sides and access is tricky in that specific area. Other highlights were Virginia's and male MacGillivray's Warbler, and 9 species of Sparrow. All total, we found 63 species. eBird Checklist: https://ebird.org/checklist/S68926129 Good Birding!

[cobirds] Rosy-Finches in Colorado - Colorado Parks and Wildlife needs your help!
Hello CoBirders! It’s that time of year again when for the temperatures start to drop, snow begins to fall, and for those of us in the high country, Rosy-Finches begin to visit our feeders. This winter, Colorado Parks and Wildlife and our partner organizations are continuing our efforts to monitor Rosy-Finches throughout the state and we need your help! Over the past 18 months, trained banders have attached colored bands to the legs of Rosy-Finches in various portions of the state and now that the birds are beginning to flock up, we hope that you will be able to report any banded birds you see at your feeders. What should you be looking for? The vast majority of our banded birds will have a small metal band placed around both their right and left legs. The band is free to move up and down as well as turn left and right and will most likely sit just above the foot. It is often easiest to see the bands when the birds are walking on the ground, or perched on a hanging feeder. Of the two bands, one will be silver, while the other will be a color that we have associated with a particular region of the state (see below for the list of possible colors). Even though you may not always be able to get good views of both legs we are still interested in hearing that you have a banded bird visiting your feeders! - Where to report? Please send an email to rosyfinchreports AT gmail.com - What to report? - Date - Location (as specific as you are willing to provide if a private residence) - Number of total Rosy-Finches in the flock (estimate) - Species of banded Rosy-Finch - Number of Banded Rosy-Finches - Color of *RIGHT *leg band (Red, Silver, Black, Blue, Green, Purple, Gold) - Color of *LEFT *leg band (Red, Silver, Black, Blue, Green, Purple, Gold) Our researchers will be able to use this information to track the movements of our banded birds, begin to understand flock dynamics, and estimate population size and survivorship. Even in the short time we’ve been tracking these birds, we’ve had several exciting findings and with your help we can learn so much more about these remarkable alpine birds. Please share this message with any neighbors or friends that may keep bird feeders so that we can collect even more sightings. If you have any questions about reporting banded birds, the details of the research we are conducting, or Rosy-Finches in general, please do not hesitate to ask. Thank you for your efforts and willingness to assist our project!

[cobirds] Re: South Platte Rez county line and eBird
Hey all, This is another great example where eBird reporting guidelines and ABA report guidelines don’t perfectly mesh. Strictly speaking, according to ABA guidelines Scott’s original post is correct. Standing in the SW corner of South Platte Res. and viewing the YBLO which is in the Arapahoe Co. portion of the res does not count as a Jefferson Co. bird. Anyone who keeps strict ABA county lists would need to walk to the Arapahoe Co. side of the reservoir or wait for the bird to move into the JeffCo side of the reservoir. EBird isn’t necessarily focused on checklists as they pertain to geopolitical borders and the ABA guidelines as they pertain to said borders. The scientific data set that is eBird is intended to be analyzed with distance travelled, duration of observation, and number of observers in mind (assuming you report all observed birds (I.e. a complete checklist)). In this sense, eBird absolutely wants to know that you saw a YBLO from the SW corner of the reservoir, even if it’s in the Arapahoe Co. portion of the reservoir. By indicating a complete checklist you are affirming that you saw all birds that you reported and reported all birds that you saw from a given location and given distance travelled. This then becomes a valuable piece of information within the eBird data set. As Andrew noted, if you view the bird from the “wrong” side of the county line and want to preserve the integrity of your ABA county list on eBird, omit the YBLO but mark your checklist as incomplete. Perhaps this is needlessly complicated but it’s one of many examples where ABA birding and citizen science birding butt heads. At the end of the day, we’re all lucky to see a darn good bird at a relatively close distance, which is all I could want.

[cobirds] Re: Harris's Hawk, Fort Collins
At 11:15 the bird continued in a tree to the west of the Rest stop/welcome center at Prospect and I-25. Shortly there after the bird moved twice to trees just north of prospect, (the trees just north of the bluish-gray house). -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Chico Basin Ranch Banding Report - Final Summary
Well that's a wrap folks. We finished up the 2017 season on Friday after a bit of a rollercoaster week. We started the week well with 61 and 62 birds banded on Monday and Tuesday but followed it up with only 7 birds on Wednesday as rain forced us to close the nets after 45 minutes. Thursday was back up into the low 40s but Friday, our last day was a wash as more rain kept us closed. In Week 5 we banded 166 birds including our first *Brown Creeper, Cedar Waxwing, Curve-billed Thrasher, Downy Woodpecker, *and both *Red-shafted and Intergrade Flickers. *We also had our first *Least Flycatcher* of the fall, the station has caught one every year since it's opening and we managed to get this fall's bird on the last day of banding. Season Recap: 911 birds of 60 species through 5 weeks of banding. Two station firsts: *Baltimore Oriole *and *Pacific Wren.* Other Notables: *Yellow-bellied Flycatcher, Sharp-shinned Hawk *(2)*, Red-eyed Vireo *(3), *Bewick's Wren, Nashville Warbler, Virginia's Warbler, *and a *Calliope Hummingbird* (unbanded). *Wilson's Warblers*, as expected, made up the bulk of our birds. We banded 291 of them this fall. *Lincoln's Sparrows, Orange-crowned Warblers, and Ruby-crowned Kinglets* also made up a large percentage of our birds. Interesting birds that we never caught but were seen in and around the station included a *Pygmy Nuthatch, Evening Grosbeak, Red-headed Woodpecker, *and of course, David Tønnessen's *Tropical Kingbird. * Thanks to everyone that came down to the station and shared our birds and we hope to see some of you in the Spring.

[cobirds] Sandhill Crane Movement - Chico Basin Ranch, El Paso/Pueblo County
After hearing flocks of Sandhills moving south all morning long during our banding session at Chico Basin Ranch, I decided to do a bit of a "Crane Watch" in the afternoon. Between 3 and 4 pm I tallied 1236 birds moving south in 6 - 8 groups. Most were in the 100 - 150 bird range, with one or two pushing 250 individuals. Things tapered off pretty quickly after 3:30 or so, and I think I only heard one or two more flocks the rest of the day. This was the first day that we've seen any major movements. Furthermore, visiting birders reported significant raptor movement with Swainson's, Red-tailed, Cooper's, and Broad-winged Hawks moving south. On my watch, I also had ~50 Turkey Vultures on the move. Should be interesting to see what movement tomorrow brings. Good Birding, Aaron Yappert -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Chico Basin Ranch Banding Report - Week 4
Hey All, It was always going to be difficult to top the Pacific Wren and Yellow-bellied Flycatcher of last week, but two days of rain really made this week a slow one. Numbers were mediocre Monday and Tuesday, with midweek rain Wednesday and Thursday. Things picked back up Friday with lots of late-morning/early afternoon action and Saturday ended up being our busiest day of the season thus far with 72 new birds banded. Notables for the week were our first *Golden-crowned Kinglets* (3) of the season and a *Sharp-shinned Hawk*. Otherwise it was the usual suspects. Season Totals: 745 Birds of 53 Species This will be the last week of banding, and the station will run Monday through Friday 7:00 am till 11:30 am, weather permitting. We love to share our birds with the public so feel free to come by. Please make sure to check in at the Ranch office before visiting the station. Lastly, be aware that the Ranch uses the banding station as an educational opportunity for a variety of school groups or other interested organizations so after 9 am the station may be filled with wide-eyed youngsters.

[cobirds] Boyd Lake SP/Horseshoe Lake
This afternoon I had 8 Common Terns at the Boyd Lake SP swim beach and four Sabine’s Gulls at Horseshoe Lake. No sign of the Mew Gull previously reported in this area, but most of the Gulls at Horseshoe were quite distant.

[cobirds] Chico Basin Ranch Banding Report - Week 3 - YBFL, PAWR!
Hey All, We wrapped up week 3 today with a drizzle and a shortened banding session but otherwise had a excellent week. Wilson's Warbler's are still our primary bird, but we're starting to see the Juncos, White-crowned Sparrows, and Chipping Sparrows move through. We banded 198 birds this week, of 28 species, including our first *Mountain Chickadee*, and *Pine Siskin* of the fall. More importantly, on 9/20, we caught, but left unbanded, a *Yellow-bellied Flycatcher*! We weren't perfectly confident on the ID at the time, and needed to release the bird to minimize stress, but after consulting with other experts, our measurements and photos proved to be to conclusive. This would be the 13th or 14th Colorado record if accepted. Here is our eBird checklist with photos: https://ebird.org/ebird/view/checklist/S39320511 As if that wasn't enough, on 9/23 (today), we caught a *Pacific Wren*, a first ever for this banding station! Again, here is the eBird report with photos. http://ebird.org/ebird/view/checklist/S39349076 Season Totals: 580 Birds of 48 Species The station runs Monday through Saturday, 7:00 am till 11:30 am.

[cobirds] Chico Basin Ranch Banding Report - Week 2
Hey All, Week two just wrapped up here at Chico Basin Ranch. Some personnel changes and very warm days saw reduced capture counts for most of the week. Friday was our slowest of the season, only banding 15 new birds. Fortuantely, things picked back up today with the return of some cooler temps and we banded 49 new birds. More importantly, we caught the station's first ever *Baltimore Oriole, *bringing the station total to 152 species over the last 15 years. The 75 visiting Girl Scouts were rightfully excited by the adult male's bright plumage. We also banded our third *Red-eyed Vireo* of the season. Season Totals: 388 birds banded of 43 species. The station runs Monday through Saturday, 6:30 am till 12 noon. We love to share our birds with the public so feel free to come by.
