Sayornis saya saya
Status: Common regular spring migrant west, uncommon central, rare casual elsewhere. Fairly common regular breeder west and south, rare casual east. Common regular fall migrant west, uncommon west-central, rare casual elsewhere.
Documentation: Specimen: UNSM ZM6369, 20 May 1900 Sioux Co.
Taxonomy: Four subspecies were recognized by Pyle (1997), but both Clements et al (2016) and Gill and Donsker (2017) recognize only two: saya of Alaska, western Canada, western USA, to southern Mexico, and quiescens of Baja California, Mexico. Nebraska birds are saya (Rapp et al 1958).
Spring: Mar 17,18,20 <<<>>> summer; Mar 17,18,20 <<<>>> 1,2,4 May (southeast)
There is an earlier report 13 Mar 2016 in Deuel Co.
Migrants occur east of the breeding range on occasion except for the southeast but are not numerous. Arrival is in late Mar, although there are earlier reports 2 Mar 1950 Adams Co, 11 Mar 2008 Fillmore Co and 15 Mar 1987 Polk Co.
Reports south and east of Polk Co are as follows: 15 Apr 2018 Lancaster Co, 25 Apr 2013 Jefferson Co, 25-29 Apr 2016 Pawnee Lake, Lancaster Co, 28 Apr 1955 Lancaster Co, 28 Apr 1988 Douglas-Sarpy Cos, 29 Apr 2013 Sarpy Co, 1 May 2011 Washington Co, 2 May 1952 Saline Co, 4 May 2013 Sarpy Co, 15 May 1966 Lancaster Co, and 23 May 1991 Sarpy Co.
- High counts: 18 in western Banner Co 4 May 1997 and 11 in southern Kimball Co 8 May 1998.
Summer: Say’s Phoebe breeds commonly throughout the drier areas in the Panhandle and southwest, with lower numbers in the south and only sporadic breeding in the east. It is absent from the Sandhills and southeast. Distribution in the northeast has fluctuated considerably historically, extending as far east as Cedar, Polk, and Cuming Cos and south to Adams and Hamilton Cos. McClure (1946) found that in central Nebraska in the early 1940s, there were 4.6 Say’s Phoebes per Eastern Phoebe, but during periods of population decline it has been limited essentially to the Panhandle. There is some evidence that easterly nesting is sensitive to wet and dry 20-year climate cycles (Kent and Dinsmore 1996, Schukman and Wolf 1998), with easterly nesting in drier periods. It was “on the increase” in the Adams Co area in the 1920s (Jorgensen 2012) and common in central Nebraska in the early 1940s (McClure 1946); there were many summer records in the 1960s, even as far east as Cuming Co (Ducey 1988; Short 1961), and again in the 1980s and 2000s (see below).
Easternmost nesting records are from Dixon and Polk Cos. Mollhoff (2016) showed confirmed breeding in the period 2006-2011 in Cedar and Wayne Cos. At least one bird summered in southwest Dixon Co 1997-99, with sightings of single birds 28 Aug 2002, 9 Jul 2004, and 25 Aug 2011. Jorgensen (2012) summarized its occurrence in the Rainwater Basin, citing numerous records from the 1920s through 1970s. In Polk Co, Say’s Phoebes were present each year in the period 1984-89, including confirmed breeding in 1985 (Mollhoff 2001, Williams 1985), and there were reports from Hamilton Co in 1985 (Bennett 1986) and York Co in 1986 (Bennett 1987).
Currently, breeding is regular in the Platte River Valley east only as far as Phelps Co, where an immature which may have hatched locally was seen 26 Jun 1994, a single was there 6 Jul 1996 (Grzybowski 1996) and a territorial pair, along with possibly three additional birds, were sighted in southwest Phelps Co Apr-May 2003. Singles were reported at Sumner, Dawson Co 9 Jun 2013 and in Phelps Co 13 Jun 2008. Further east, a pair appeared to be nesting on a bridge in Howard Co 8 Jul 2016.
Breeding season reports from the north-central are lacking; northernmost is of a nesting pair at the edge of the breeding range in Broken Bow, Custer Co 4 Jul 2008. The only known nesting attempt in Garden Co was unsuccessful at Crescent Lake NWR in 1980 (Williams 1980). Scattered recent breeding season reports from the eastern Sandhills and eastern Niobrara River Valley are of singles in Hooker Co 8 Jun 2010, Antelope Co 28 Jul 2009 and 6 and 12 Jun 2010, two sightings in 1982 in Brown and Cherry Cos (Brogie and Mossman 1983), and sightings in Brown Co 3 Jun and 27 Jun 2018, Rock Co 19 Jun 2012, and Niobrara SP, Knox Co 12 Jun 2011.
Despite fluctuating numbers and range, BBS trend analysis shows the species has increased annually by 3.20% (95% C.I.; 0.95, 5.48) during the period 1966-2015 (Sauer et al 2017).
- Breeding Phenology:
Nest Building: 20 Apr-5 May
Eggs: 10 May-4 Jul (commonly double-brooded)
Nestlings: 6 Jun-16 Jul
Fledglings: 21 Jun-4 Jul
A pair in Kimball Co had a second clutch of two eggs 29 Jun with five fledglings from the first clutch nearby, and a nest with 3-4 young in Hitchcock Co 16 Jul was probably a second clutch (Mollhoff 2008).
Fall: summer <<<>>> Oct 8,9,10
Departure is usually completed by late Sep; later reports are 19 Oct 1965 Lincoln Co and 29 Oct 1964 Lincoln Co. Peak movement is late Aug-early Sep.
Say’s Phoebe is rare in fall away from the Panhandle and the west-central, with most of the few records from known breeding locations. This is especially true in the east, where there are 13 reports in the period 16 Sep-9 Oct, and even in the central, away from Lincoln Co, there are only 14 reports, all in the period 1-30 Sep. There is an amazing late date 27 Dec 2013 Keith Co.
- High counts: 10 in Kimball Co 27 Aug 2006, 8 in Scotts Bluff Co 1 Sep 2001, and 7 on Stateline Road, Sioux Co 4 Sep 2017.
