The first nest was found on March 18th, containing seven eggs, and hatched 18 days later. The nest, then, was actually started during the first week of March. Nests with e<j'gs were most numerous during tin- early part of April (Figure -'5). The majority of the nests contained .â and were under incubation by April 7th. The peak of egg laying came between March 25th and April 10th. The peak of the hatch came between April 15th and April 30th. This compares favorably with the study made by Dow (1943)..
