This was an extremely interesting specimen. The turkey landed, showing tail feathers in the snow... then proceeds to walk, only clearly registering its left foot.
In several parts of the several meter-long trail, I noted holes and scuffs in the snow that seemed reasonable for placement of a right foot (or stump). In particular, note the hole between the tail feather imprints and the first left track.
2" long classic bird track with slight inward curvature to T1-T3 line, plus slight forward curve along T2-4 line. Present near Visitor Center, under Mendota bridge.
Scat. Loads of tracks nearby.
Left hind/front right pair of tracks from a raccoon classic overstep walk pattern.
Maybe NOMO or CASJ? Old nest 4ft up in shrubby coast live oak
Tracks and trails in about 1 inch of heavy wet snow (birds were observed making these trails.)
Square hole drilled in tree; pileated woodpeckers (and others) are present
Sizeable scat containing bone fragments and deer fur (?)
Lots of mourning dove feathers. On inspection, looks like there may be two (or more) individuals here, with some juvenile and some adult feathers present in the left secondaries (see pic 5 for comparison). Scattered over a wide distance, suggesting that the predator plucked from a tree.
Likely evidence of a predation event. Downy body feathers caught on thorny branches (pic 4) and flight feathers fallen below (pic 5), so possibly plucked from above. Clean unbroken shafts suggest an avian predator.
Oval galls on what I believe is goldenrod. Doesn't look round enough for goldenrod gall fly and looks too pronounced for Epiblema scudderiana.
