Behlo 1934 Berkeley, California - MVZ UC. 164 Aug. 6. Lomi W. Oroville, Butte Co., Calif. aug. 6 ? ad. H72 Otororis alpestris rubea 25.7g. Primaries: 9,8, old. 7 still in papillae, rest new Secondary no1 new, 2 still in sheath, rest old, no. 7 of the old 3 is old, 8 + 9 new. Alula old. covets all new except outer two primary covets. Tail: center pair half way grown, rest pair about same, 3rd pair from center just starting or is still sheathed, the outer three pairs are old. This proves that the feather replacement starts from the inside and progresses outwards. I am not sure yet whether the middle pair drops out or the 2nd pair. There seems a little unequal growth exhibited in the members of the second pair. Unders tail covets all just protruding from sheaths. Upper tail feather nearly full grown. Some of breast feathers old. Chest & side new. Back all new. Head most retarded - Forehead and front of head feathers coming in new. Rear of head badly worn and showing no replacement. Base of skull and sides of neck old + faded. New yellow feathers coming on chin + throat. This bird has lost both the tarsi and foot pads a great pad has developed on the other foot the nails are gone and pads have developed there too
