Literature on productivity and. survival

In terms of over-all nesting success, the productivity of 
Zenaidura macroura has been well studied (table 42). Although about 
per cent of functional nests (those in which one egg has been 
laid) will hatch as a general rule, as low as 37 per cent and as 
high as 58 per cent have been found in different years |(McClure 1941).

S. He Low (1935) has published a preliminary report on the 
survival of unaged birds banded by the Austin Ornithological Research 
Station on Cape Cod, Mass. Four years of recapture work, he reported, 
suggested a trend of survival reaching zero about the ninth year ( ? 
after banding). A recalculation of the data (table 3) indicates that 
these birds disappeared at a mean rate of about 0 per cent per year. 
More recently, 0. L. Austin, Jr. (1951) has summarized 20 years of 
gata on mourning doves at this station. For 269 adult birds, the 
mean mortality rate was 52 per cent per year; for 105 young birds, 
the first-year mortality rate was 75 per cent. 
Banding work in North America 
From 1926 to 191 inclusive, 100 banders ringed 9929 juvenile 
doves; this banding total yielded 371 recoveries (3.7 per cent). Im 
portant banders of young birds in this period were E. ©. Anderson (129) 
in Souta Dakota, O. L. Austin and associates (428) in Massachusetts, 
F. W. George (21,3) in South Dakota, J. W. Kistler (535) in North 
Carolina, F. E. and C. ©. Ludwig (46h) in Michigan, J. A. Neff (1487) 
in Califomia, A. M. Pearson and H. S. Peters (568) in Alabama, E. 
Preston (17) in North Dakota, "T. G. Scott" (1551) in Iowa, C. Stan- 
nard (1869) in Arizona, and I. Sturgis (287) in Missouri. Stannard 
obtained 63 recoveries up to 1946, Neff 47, and Scott 63. I presume 
that the banding work credited to Scott in the Fish and Wildlife Ser- 
vice files was largely carried out by H. &. McClure (see above).
