Oh, I hope Brenda and Steven's optimism about nighthawks is justified. They are a favorite species of mine, and I've watched their steady, steep decline here--I live not far from Brenda and Steve--and elsewhere over the years. I won't pass along sad musings about this dramatic species, but below is part of my entry about it in my book about local birds, intended as a neutral view. --Bill Whan Common Nighthawk Chordeiles minor*. In 1874, Kirtland et al. (263) wrote that it “deposits its eggs on the bare ground, often in the middle of a field,” and in Wheaton’s day too nests of nighthawks were usually found here in settings such as fallow fields; an incubated egg set of two collected 6/12/1890 (OSU Museum #E3311) in Franklin County, for example, was found in “a slight depression in the ground.” Bales’s egg collection at OSUM includes 16 sets collected from ground nests dating from as late as 1913; the seventeenth, from 1931, was found on a roof. Nighthawks nested in abandoned quarries on Kelleys Island in Lake Erie as recently as 1954 (Dexter 1956:13). As early as 1903, however, Dawson (343) was to write “[i]n Columbus it is a familiar feature, hawking fearlessly above High Street, and nesting, as in many other cities, upon the tarred and gravelled roofs of flat-topped buildings.” Such roofs had gradually come into wide use after the Civil War. Hicks (1935a:156) pronounced nighthawks present, relying on such a nesting strategy, in nearly every Ohio city with a human population of more than 5,000, often absent in smaller communities. Nests in towns grow scarcer every year, at least in part because gravel ballast is evermore seldom employed on roofs and flying insects have become less numerous in cities; increased egg depredation by urban crows and raccoons is a factor as well. Other than brooding females, generally roosts, its long axis parallel to a limb, in trees; Trautman (1940:281) wrote they much preferred black walnuts and honey locusts for the purpose, trees whose bark colorations most closely matched those of their plumage. Spring migrant flocks tend to number in the dozens at best, moving at higher altitudes than in fall. Usually arrives by 5-10 May. Very early local records come from 4/16/1899 (OSUM specimen #882), 4/18/2011 (fide M. Skinner) and 4/19/1985 (OC 8(1):23). The highest twilight counts of fall movements usually come from late August-early September, and include a description of circle-soaring by “at least several thousand” over the OSU campus 9/3/1968 (Mueller 1970), 3000+ on 9/3/1976 (Thomson 1983:206), and 2500 on 9/3/1992 (OC 16(1):21). Later in fall, 224 were observed 10/3/2006 (OC 30(1):20). One entered the OSU campus’s main library on 10/22/1965 (WCB 11:46). Record late was one seen and heard calling on 11/20/1975 at High St. and Morse Rd. (J. Stahl, WCB 1(20-21):42). Odd-looking local fall specimens from OSUM were sent to H. C. Oberholser during the 1930s and ‘40s (see for example Aldrich 1936), who identified several as western subspecies such as hesperis (#7464, 9/3/1936), howelli (#7487, 8/28/1936), and sennetti (#12021, 8/31/1938).
