Had #/p orange-skinned young, that had down tufts on spine, head, and wings. Eyes barely open. Banded the two larger ones. #40-250401 and 40-250427. #2 nest at 10' in willow. 4 eggs. ##3 & 4 - 2 fresh nests near to these two nests (6 feet away), but no eggs yet. Brewer Blackbirds - small nesting colony found at end of peninsula in scattered willows near the high water line. Grass hillsides around the area. I found that one pair had the following two nests, which were in isolated trees about 17 feet apart (by pacing). #1 - Nest cup 3 1/2" deep, rim 6 1/2' above ground. 2 freshly hatched young, and 3 eggs were in this nest. Bright orange skin. Horsehair-lined. #2 - Nest cup 3" deep, rim at 7' above ground. 5 nearly fully-feathered young in this nest. Parents were busy feeding them. Largest young was nearly 4 inches long, and the smallest 2 3/4" long. It looks as if all these young will leave the nest. Primaries were 2" long, the tail up to 3/4", and the young all had brownish eyes. Banded with #'s 41-152107,8,9,10, and 11. Horsehair lines. Other nests nearby were as follows: All horsehair lined. #3 - at 7' in willow. Sheltered. 2 eggs and 3 young with primaries over 1/2" long, but still sheathed. Mostly downy. #'s 41-152112,3,and 4. #4 - an old nest (at least last year's) on east side of willow at 9'. Two young, well-feathered. (#'s 41-15216 and 20) #5 - another old nest just 3 1/2-4 feet apart from #4 contained 2 well-feathered young, much the same as in #2 and #4. #'s 41-152115, and 19. #6 - nest a 9 1/2 feet in willow, on NW side. 2 orange-skinned young. Primaries still sheathed. Tail about 1/16" long. #'s 41-152118 and 21.
