[cobirds] Re: COLORADO RARE BIRD ALERT for Thursday, May 21, 2020

Re: Black Vulture Wheatridge Greenbelt

I saw this bird too, from the WGB bike path at 10 AM, over Golden, circling higher and seemingly headed north.  Most striking was the extremely short tail.

Next, a large white wing patch repeatedly visible in one wing.  When I got home, after consulting guidebooks, I talked myself out of

reporting a Black Vulture, opting for an immature Golden.  The bird seemed huge (and I had a Swainson's Hawk in the same field of view to help).  Also, the

white patch in the wing was quite large, and not, I think, in the wingtips but more in.  

On the other hand, no white band was seen in the tail, and the tail was just sooo short.

The Colorado Rare Bird report is an informational service. 

 

Because of statewide coronavirus "Safer at Home" orders, this report is meant to keep homebound readers abreast of rare bird sightings across the state during spring migration. It does NOT endorse and is NOT meant to encourage the pursuit of rare birds beyond your local area.

 

We urge readers to respect state and local restrictions on non-critical travel.

As potentially asymptomatic outside visitors, unethical urban/suburban "chase" birders who travel to more remote locales may risk exposing isolated Colorado populations to the virus.

 

To ensure your safety and that of others while birding, do the right thing. Please practice physical distancing, wear face masks and follow all other Covid-19 precautions.

Birders have been helpful by reporting updates to COBirds. Thanks!

CAPITAL LETTERS denote very rare species, as listed by the Colorado Bird Records Committee at the CFO website.  The Committee requests you please fill out a report for sightings of these birds.

(*) indicates new information on a species.

Spring migration notes

Colorado's remarkable 2020 neotropical warbler migration is waning.

Many Flycatchers, vireos, thrushes, tanagers, sparrows and orioles are moving; some are already on breeding grounds.  Shorebird sightings have declined.

Note: In an attempt to limit an already-overlong daily report, we are omitting most reports of these recently listed species from the daily report (exceptions being when they are extremely rare for a given county):

Gray-cheeked Thrush, Northern Waterthrush, Black-and-white Warbler, Tennessee Warbler, Nashville Warble, Hooded Warbler, Northern Parula, Chestnut-sided Warbler, Blackpoll Warbler, Palm Warbler, and Summer Tanager.

Please continue, however, to report these birds and other finds on COBIRDS.
