I spent a few hours checking on parks along the Olentangy River in urban Columbus, starting at Antrum Lake, then visiting Whetstone Park, and finishing at the OSU wetlands. Migrant numbers were strongest early (at Antrum Lake), and declined noticeably as the morning wore on. By the time I reached Whetstone, I didn't find the numbers or diversity that Paul & Jeff had there earlier. I would guess that this good weather allows the birds to keep moving. Highlights included: Horned Grebe - a nice Spring-plumaged bird on Antrum Lake Red-shouldered Hawk - a calling bird in the Whetstone ravine near High St. E.Wood Pewee - single bird calling at Whetstone (1st of Spring, surprisingly) Least Flycatchers - 2 at Antrum Lake, 2 at OSUwetlands Crested Flycatchers - 2-4 birds in each park E.Kingbird - 2 at Antrum Lake Blue-headed Vireo - 1 at OSU wetlands Yellow-throated Vireo - 1 at Antrum Lake Warbling Vireo - 26+ between the 3 parks; 1 was finishing up a nest at Whetstone Red-eyed Vireo - 10+ between the 3 parks Swainson's Thrush - only singles at Antrum & Whetstone Wood Thrush - 8+ between the 3 parks, with 5 in the Whetstone ravine Blue-winged Warbler - 1 at Antrum Parula - singles at Antrum, Whetstone Yellow - several at all 3 parks; OSU wetland had the most (4) Nashville - 2-4 in each park, often giving surprisingly different songs Tennessee - 3-6 in each park; second most common warbler of morning Black-thr.Blue- singing males at Antrum, Whetstone (ravine) Magnolia - 2 in Whetstone ravine Black-thr.Green - 4+ at Antrum Lake Blackburnian - singing males at Antrum Lake & Whetstone Chesnut-sided - 2-4 in each park Yellow-throated - 1-2 in each park Bay-breasted - single male at OSU wetlands Yellow-rumped - 5-7 birds at each park; most common warbler of morning Palm - 3+ birds at Antrum Lake Redstart - singing males, 2 at Antrum Lake, 1 at Whetstone Ovenbird - 1 at Whetstone (ravine) Common Yellowthroat - 3+ at OSU wetlands Rose-br.Grosbeak - singing males at Antrum Lake & Whetstone Indigo Bunting - 2-5 at every park Baltimore Oriole - 25+ between the 3 parks ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
