The Colorado Rare Bird Report is an informational service.
Because of statewide coronavirus "Stay at Home" and "Safer at Home" orders (depending on where you live), the purpose of this report is to keep homebound readers abreast of rare bird sightings across the state during spring migration. It does NOT endorse or encourage illegal travel to see or "chase" rare birds beyond your own permitted area.
We urge readers to respect state and local restrictions on non-critical travel and limits on outdoor activities that include birding. Please bird ONLY at or close to home and ONLY with universally promoted safety precautions, including "social distancing" and face coverings. Or, as Dave Leatherman noted, "Be like a Cedar Waxwing . . . very compliant in wearing their masks."
_______________________________________
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.
(*) indicates new information on a species.

Spring migration notes:
Shorebirds are passing through, with 23+ species reported to eBird recently, including multiple Whimbrel sightings, large flocks of curlews and godwits. It's Caspian Tern time too. Reports of Gray Flycatchers and Black Phoebes were widespread. Some Cassin's Finches continue to be reported, but fewer than last week. Hummingbirds are starting to show at feeders. Sparrows and longspurs continue to move through. Warblers are arriving!!!! Migration really picked up yesterday, with both returning Colorado breeders and "overshoots" from the southeast like Louisiana Waterthrush, Yellow-throated and Hooded Warblers. Highly prized "Eastern" warblers are flowing into SE Colorado, and soon we'll find them farther north. Exciting!
What's in your yard or near your home? Let us know on COBirds.
