Observation details

In same general area as non-singing DUFL. Frequently making "peet" call. Shorter tail evident in comparison with DUFL. Seen carrying materials to a developing nest on top of a horizontal limb of a Douglas-fir, ca 1-2 m from the bole. Several hours later, on the return, I was not able to locate the nest in the Douglas-fir. Ca 20 m west, on the trail, I noticed a nest that seemed to correspond in size and shape. I photographed it and now, upon comparison of the two photo sets, I am fairly sure that it is the same nest. After finding it on the ground, I looked carefully in the tree, hoping I would find the HAFL nest still up there, but did not - I am reasonably sure I did not overlook it, since I remembered quite well the general area where it had been. I have no way of knowing how the nest came to be on the ground, especially so far away. Predator? Wind? Competing HAFL? CEDW taking nest material? I really hope that my presence did not lead a predator or other disturbance to the nest. When examined on the ground, the nest seemed to be composed of a layer or old, dead grasses on the outside, with a substantial amount of Bryoria lichens inside. There was a bit of an indentation in the top, but a cup was not yet well-developed.
