Also the excrement of the nestlings is not so securely enclosed
by "skin" as before and requires more delicate handling on the part
of the parents, though the method of disposal is the same.
Later in the afternoon an escaped tame canary perched near the
top of the old oak and called. This attracted the Greenbacked
Goldfinches, one of whom perched about 2 feet from the canary for
perhaps 10 minutes, the latter leaving first. The canary broke
into full song and as soon as Brownie, who was in the glade preening,
about 10 feet from me, heard the song, he raised his head and listen-
ed for a few moments, then ran to the trunk of the old oak and rapidly
climbed up into its branches to within about 10 feet of the canary,
where he paused and watched him, then, apparently satisfied, returned-
ed to the same branch of the sage on which he had been preening and
completed that operation. After that he took worms to the nest.
The canary had evidently been at liberty for some time, for
it seemed perfectly at ease and when it flew away, it seemed as
vigorous as any wild bird, flying like a linnet.(House finch).
oldest night November 7th. (Sunrise 6:40) (Minimum during the night 46)
for many months.
At 8 A.M. both thrashers seemed to be waiting for me near the
nest. B came at once without food and we gave the young, who appear-
ed sluggish, worms. G was picking up things below the platform and
when she came up, had a lot of those small white grubs. It looks
now as if they do come out of the acorns and the thrashers pick them
off of the ground. G continued the feeding operation with meal-worms.
Jerusalem cricket. At 9:10 A.M. Brownie brought a Jerusalem cricket to the nest
within 5 minutes after I had given him worms in the glade. G then
brought a cut-worm and 3 of the small grubs and followed up with meal-
worms from the box. I had put two of the adult beetles in the box
to see what the thrashers would do with them. Although the adults
eat them when they have a chance to break them up on the ground,
