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. For more information on birds seen today, go to cobirds.org and scroll to the bottom for “Recent eBird Sightings.” _______________________________________ 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. ___________________________________ Rare birds and some out-of-place or out-of-season birds include: MEXICAN WHIP-POOR-WILL (Fremont, SE CO) BLACK VULTURE (*Jefferson, Pueblo) ANNA’S HUMMINGBIRD (Jefferson) BLACK PHOEBE (Rio Grande) Vermilion Flycatcher (SE CO) Scissor-tailed Flycatcher (Jefferson) Yellow-throated Vireo (*Denver) Winter Wren (Jackson) Sedge Wren (Weld) Wood Thrush (SE CO) McCown’s Longspur (Larimer) Field Sparrow (Larimer) White-throated Sparrow (Yuma) EASTERN MEADOWLARK (Lilian’s) (Larimer) Baltimore Oriole (Custer) SCOTT’S ORIOLE (Broomfield) LOUISIANA WATERTHRUSH (Jefferson) Golden-winged Warbler (El Paso, Jefferson, Larimer) Blue-winged Warbler (El Paso, Fremont) Mourning Warbler (Larimer, Yuma) Blackburnian Warbler (Denver, Larimer) Black-throated Blue Warbler (Cheyenne, SE CO) Pine Warbler (Boulder, Jefferson) Yellow-throated Warbler (Jefferson) Magnolia Warbler (Arapahoe, Denver, El Paso, Larimer) Bay-breasted Warbler (Larimer, Pueblo) Black-throated Gray Warbler (Denver, Jefferson, Pitkin, SE CO) Scarlet Tanager (El Paso, Rio Grande) Northern Cardinal (Boulder) ____________________________________ SOUTHEAST COLORADO: Rare Birds located within Baca, Bent, Kiowa, Otero and Prowers Counties are listed below without location in an effort to limit the temptation for more birders to chase birds being found primarily by Front Range birders traveling to these small communities in violation of statewide “safer at home” regulations.
