to the nest--no signs of Greenie. Earlier in the morning a loud thrasher call was heard. During the day Brownie was in constant attendance at or near the nest and seemingly much pleased to have me assist in feeding. I am supplementing the supply of meal-worms with scalded ant eggs mixed with soft food. This mixture is fed with the "squirt gun". Even when B is feeding them at the same time, the young bird not directly concerned with Brownie, reaches out to me eagerly for food. Brownie watches closely, picks up all the crumbs and looks down their throats as on former occasions, to see if I have made a good job. He also picks off the small particles of food that adhere to the glass tube, sometimes giving them to the nestlings and sometimes eating them himself. He likes to be fed with the gun himself. He does not hesitate to leave me alone at the nest and walk about on the platform at my feet, looking up at me and showing no concern. There have been no signs of Greenie all day. March 31st. First sign of fear At 7:30 A.M. B was at the nest. The young ones squealed when by young, but they first saw me and crouched low in the nest at first, but almost realize error. immediately began reaching for food, singing the fairy chorus. Test to see When I saw B coming, I descended as I wished to see if he would recognize if B knows young have been fed nise that the nestlings had been well fed, or continue the operation. He took up one small load, and on his return, ate a few himself, taking up only two. Coming back he ate a few, took up one or two, then ran toward the oval lawn, where he called once: Too-wheat-you, weet, weet, weet. B calls once (for G?) How do parents know when young have enough? I have wondered how the parents knew when the chicks had had enough food: by the actions of the young, their own sense of having labored sufficiently, or what? It appears from the foregoing that they can tell irrespective of the amount of food that they themselves have administered. Brownie approves highly of my help. Youngsters associate me with food. B likes to be fed with squirt gun! No G!
