A simple animal support for convenient weighing
A simple animal support constructed of web belts to hold skittish pigs for weighing was developed. The support is easily made, noninjurious to the pigs, and compact, facilitating rapid, accurate weighing. With minor modifications, the support can probably be used in weighing other animals.

Body weights of newly hatched Anatidae
As early as 1928 (E.C. Meyers, Auk, 45: 334-388, 1928) investigators realized the importance of bird weights and appealed to ornithologists to record and publish records of these. Practically all of the weights of waterfowl that have been published, however, have been of adults or grown young (see F.H. Kortright, The ducks, geese and swans of North America, Amer. Wildl.

Development and maturation of primary feathers of redhead ducklings
A comparison of the maturation rates of the primaries of redheads (Aythya americana) hatched very early with those hatched very late was made in the 1961 season. Primaries of the early-hatched birds emerged when the birds were 36-38 days old, those of the late-hatched birds when they were 7-10 days younger. This difference was also found in the age at first flight and the age at eventual maturatio
