that I offer them. I have not seen anything larger than a meal-
worm given to the young of this brood. They are being fed without
regurgitation. (Temp. 54--absolutely calm--sun breaking through).

The stubborn Greenie will take nothing from me while in the nest
unless Brownie is there too. Then she is a different bird.
G feeds "fly-
ing ants"? About 12 she carried a number of small insects up and fed them to
the young. They looked like the "flying ants" that the rain has
cased to swarm, although I did not get a good look at them. In
any case, the thrashers are interested in them, as they have dug
numerous small holes at various places where the "ants" are coming
out of the ground. I noticed that the Argentines are attacking
them as they come out. (Or perhaps helping them shed their wings;
as they frequently come off during the struggle (?)) Termites?
B's behavior in
feeding meal-
worms. A few minutes ago I offered a worm to Brownie on the nest. He
then promptly ate it. The second one he took, and froze for perhaps a
minute. He then backed out of the nest and tried to give it to the
chick nearest me, but abandoned the attempt and fed it to the other
one successfully without preparing the worm. (Perhaps when he froze
he was trying to arrive at a decision whether he should risk feeding
the unprepared worm, go to the ground and break it up, or eat it
himself)! Thinking that it might be that the first bird to whom the
worm was offered was the younger of the two, and therefore possibly
not able to handle so large an object, I selected a small worm and
gave it to B. This worked all right. B, considering the subject
closed, turned his back on me and settled himself deeply in the nest
with sidewise oscillations. No feeding by regurgitation there!

dropped from my fingers, she took it and held it in the tip of her
bill 7 minutes (actual timing), when she suddenly backed out of the
nest and gave it to a chick. I looked around to see if that meant
