Survival of female black ducks, Anas rubripes, during the breeding season
The Mayfield method was used to estimate the survival rate of 19 radio-marked, female Black Ducks (Anas rubripes) in southcentral Maine during 1977-80. An overall survival rate of 0.74 was estimated for the 121-day monitoring period that included the pre-laying and laying, incubation, brood rearing, and post-rearing stages. No differences in survival rates were detected among these stages. Two ins

Sampling over 33 continuous months indicated that hemoglobin, hematocrit, red blood cells, mean corpuscular hemoglobin concentration (MCHC), and thyroxine exhibited consistent circannual patterns of variation in both males and females.
