There were young about the second week of July in seven nests in a tall fir (140-150 ft) surrounded by others - firs, cedars, maple. Young are grown but have not left nest. They are fed on fish and are tall, adult-looking birds. Squirrel and Swainson's Thrush in single notes were heard. Other sounds were unidentifiable.

Grace Bell's Research Notes:

Tape Number:

M6.033(18c)

Recording Remarks:

Nagra III B, 40" parabolic reflector, 15 ips

Length:

not available

Location Description:

6:00-7:00a.m., 45-50 degrees, no wind, dull, then clear

Location Name:

Swartz Bay and Land's End Road, Victoria

General Remarks:

The birds have just returned in the last two or three days. About seven of them seem to be in the tree. The one bird which was noisy was first at the nest and then standing on it. Another bird moved around the nest and then replaced the first bird by standing on or in it. The one in the branch beside the tree spread out the long plumes on the neck, lowered the head down below its perch and clicked the bill (heard on tape). There were five birds seen definitely in the tree but as the day wore on there may have been seven coming and going. It was hard to keep track. There are at least seven birds. The click or snap also appeared to be when a twig near the nest was broken but it did not fall and I did not see it taken in the bill. Background: Traffic not too bad, Bewick, Robin, Towhee, Pileated Woodpecker, squirrel very agitated.
