[cobirds] eBird species trend maps!
Cornell eBird is just releasing species maps showing trends in abundance from 2007 to 2021. Wonderful consolidation of zillions of observations. I pulled up the map for Blue-gray Gnatcatcher. https://science.ebird.org/en/status-and-trends/species/buggna/trends-map?utm_source=Cornell%20Lab%20eNews_campaign=612a9e57e2-Cornell-Lab-eNews-November-2022_medium=email_term=0_47588b5758-612a9e57e2-306045397 This map tracks my experience of a significant decline in abundance along the Front Range. It would appear that we are on the western edge of a broad decline in abundance in the eastern US, whereas almost the entire West is showing increases. If nothing else, these maps will fuel a lot of discussion and arm-chair theorizing. -- -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Re: Help with yard bird ID--Aurora, Arapahoe County
Sure sounds like a Green-tailed Towhee, and this is just the time of year to have them coming thru. In dim light, I'm not sure the greenish color would stand out. And the behavior you describe is very towhee-like. https://www.allaboutbirds.org/guide/Green-tailed_Towhee/id# On Sunday, May 16, 2021 at 8:43:08 AM UTC-6 Jean Stevenson wrote: > Sorry no photo.

[cobirds] Northern Waterthrush: CU Boulder East Campus
Going north on the bike path that is just east of the LASP building, within 100 yards you cross a short footbridge over a small stream connecting two ponds. (A little ways farther north is the Boulder Creek Path.) This seems to be the usual spot for the waterthrush.

[cobirds] Blue-gray Gnatcatchers?
In my local patch (Bear Creek in Boulder Open Space and Mountain Parks), Blue-gray Gnatcatchers are each year one of the earlier migrants to set up shop. I have, for example, had multiple pairs by April 19. And one of the great things about this bird is how pugnacious they are; you can hardly peep without one of them popping up to glower at you. This year, to date, I have seen none along nearly a mile of nice shrubby habitat. I hope that others are seeing lots of this bird. ??

[cobirds] Northern Parula Warbler, Waneka Lake, Lafayette, CO
High in the trees, southwest corner of the Lake. The area between the lake and Greenlee preserve was just crawling with yellow-rumps and orange-crown warblers this AM, particularly on the chokecherry bushes. -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Singing Northern Mockingbird -- South Mesa Trailhead, Boulder County
I was out this morning checking on OSMP trailheads, COVID compliance (variable), levels of use (very high). While I was slowly cruising through the South Mesa and Dowdy Draw parking areas, I was hearing a mockingbird singing loudly and almost continuously. I've seen mockingbirds a couple of different years in this area, so maybe it's not surprising, but a nice sound of spring! -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Phoebe Trifecta possible?
Seeing an Eastern Phoebe this morning (Boulder Creek at 75th St.) got me thinking about Trifectas or Hat Tricks. It is getting more likely each year that someone could see the Black, Eastern, and Say’s Phoebes all from the same spot. There are several other Hat Tricks possible, at varying levels of difficulty. I’m sure many of us have seen three Jay species together. Swallows (several possible combinations). Nuthatches (red, white, pygmy)? Bluebirds (east, west, mountain)? Rosy-finches? Wrens (house, rock, canyon)? Longspurs??? We live in an area that makes several Trifectas possible that would be inconceivable in most parts of the country. I’m sure there are many additional with varying degrees of complexity.-Curt Brown -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] What hunger will drive hummers to tolerate -- Boulder
Not sure I've ever seen two male hummers drinking from the same feeder hole at the same time.

[cobirds] Good Migration Conditions Today
It does seem that the Hummingbird Highway got routed here overnight. Instead of 2-3 hummers at our two feeders, we have more than 10, far exceeding any previous count.

[cobirds] Re: Binoculars repair
I do not know of a binocular repair firm in the Denver area, but Cory Suddarth in OK has a national (and even international) reputation. If you have a pair of high quality binoculars, I think it would be well worth considering shipping them to him.
