CANADA WARBLER

Cardellina canadensis

Status:  Rare regular spring and fall migrant east, rare casual central and west.

Documentation:  Specimen: HMM 1793, 17 May 1916 Spring Ranch, Clay Co.

Taxonomy:  No subspecies are recognized (Pyle 1997).

Spring:  May 11, 11, 11 <<<>>> May 29, 29, 30

Earlier dates are 3 May 2012 Sarpy Co, 6 May 2014 Sarpy Co, 8 May 2014 Dodge Co, and 9 May 2003 Knox Co.

Migration is in the latter two thirds of May.

This species is less numerous in the midcontinent of the United States in spring than in fall. Curson et al (1994) stated that Canada Warblers tend to follow the Atlantic coast in spring but occur in higher numbers westward in fall. In Iowa, of 422 Canada Warblers banded, 302 were in fall (Dinsmore et al 1984).  This species is one of the last spring migrants to arrive.

Away from the east there few reports, including two from the Panhandle 4 May 2014 Scotts Bluff Co and 18 May 1919 UNSM ZM6913, and several from the central: May 1980 Thomas Co (Bray 1994), 19 May 1996 a male netted at Lake Ogallala, Keith Co (Brown et al 2012), and 28 May 1997 adult male netted Lake Ogallala (Brown et al 2012).

  • High counts:  3 at Walnut Grove Park, Omaha 24 May 2009, 3 at Fontenelle Forest, Sarpy Co 21 May 2018, 3 at Wyuka Cemetery, Lancaster Co 22 May 2020, and 3 at UNL East Campus 23 May 2020.
    Best spring totals are 27 in 2020, 13 in 2018, 9 in 1996, 8 in 2009 and 6 in 2005.

Fall:  Aug 21, 21, 22 <<<>>> Sep 25, 26, 27

Earlier dates are 12 Aug 2014 Dixon Co, 18 Aug 2018 Douglas Co, 18 Aug 2018 Platte Co, and 19 Aug 2012 Knox Co.

A later date is 12 Oct 2019 Dakota Co (ebird.org).

Migration is from mid-Aug through late Sep.

An amazing showing was the 11 reports, involving a total of 14 birds, all in the east, 31 Aug-25 Sep 2016. This was eclipsed, however, by the 33 reports involving 35 birds in 2019, again all in the east 24 Aug-12 Oct.
