September 12 [Day 19] The temperature reached 21C from a low of 13C under completely cloudless skies all day. Winds were WNW to W gusting to 28 km/h until 1500 when winds became light shifting to the S then after 1710 to the E. Despite the apparently favourable winds the first migrant raptor did not appear until 1208 and steady movement didn’t start until after 1300, after which birds moved fairly strongly until 1754. The flight was again dominated by Sharp-shinned Hawks (33) and Cooper’s Hawks (11) with a leavening of Broad-winged Hawks (2), American Kestrels (4) and a juvenile Peregrine Falcon at 1447. Detection of the birds flying high against a pure blue sky was very challenging but thanks to the sharp eyes of Phil and Keith fewer birds were missed than would have been had I been alone. Songbird movement was again dominated by Yellow-rumped Warblers (56) but the most remarkable sight was a single flock of about 25 Townsend’s Warblers moving through at 0930. The species had not been recorded at the site for 7 days and the previous highest daily count this season was 8 birds. It was certainly by far the largest flock of the species that I have ever seen. A single female Evening Grosbeak at 0935 was the 75th bird species recorded this season. 12.25 hours (237) SSHA 33 (229), COHA 11 (68), NOGO 1 (37), BWHA 2 (29), RTHA 4 (52), GOEA 1 (38), AMKE 4 (19), PEFA 1 (9) TOTAL 57 (580)
