Nest Sites and Eggs of Kittlitz's and Marbled Murrelets

Abstract
Fourteen known and 3 probable nests of Kittlitz''s murrelet (B. brevirostris), and 8 known and 1 probable nest of marbled murrelet (B. marmoratus) were reported. Nests of Kittlitz''s murrelet tend to be at higher elevations and farther inland than those of marbled murrelet. Kittlitz''s nests have much less vegetative cover than marbled nests. Nests of both species are generally a short distance below a peak or ridge, Kittlitz''s on the ground and marbled either in a tree or on the ground. The eggs of the 2 spp. are similar in color and their mean dimensions are not separable statistically. Findings support the idea that Kittlitz''s fledglings commonly get to the sea by way of streams.
