Hi, Tweeters:

Our apologies for the delayed posting. Here are highlights from the spring
raptor migration sightings at Cape Flattery.

The observations covered 43 days from 20 March through 1 May 1997, with 216
hours of observation at one of several sites on Bahokus Peak, Cape Flattery.

Total raptor sightings 7255 (excl Bald Eagles, heavily biased by local
resident birds)
Buteos 5752 (essentially all Red-tails, but incl. 3 Swainson's)
Golden Eagles 43
Accipiters 936 (incl. 783 Sharp-shins, 65 Cooper's, 27 N. Goshawks)
Falcons 80 (incl. 25 Kestrels, 28 Merlins, 23 Perigrines)
Turkey Vultures 342
N. Harriers 21
Osprey 32 (incl. local nesting arrivals)

The peak day was 4/6/97, with 2130 sightings. Other high days were 4/5 with
1125, 4/21 with 553, 4/18 with 483, and 4/4 with 414.

Len Liu was the principal observer on site, assisted by volunteers from
various Olympic Peninsula and other Northwest places. The study, one of the
Western migration site studies of HawkWatch Int'l, was facilitated by a
research agreement with the Makah Nation and coordinated locally by Virginia
Clark, Ken Wiersema, and Welden Clark. Housing for the full-time observer
was provided by the NOAA Olympic Coast National Marine Sanctuary. We
appreciate the generosity and interest of the Makah Nation and its natural
resource staff in providing access to non-public lands for our study.

An Excel spreadsheet with detail by species and day can be provided by email
(MIME attachment) to those interested (Please specify whether Excel 97 or
4.0).
