hrota) nested in late springs on Southampton Island (64[degrees] N), and O'Briain et al.
On Banks Island, both of these effects were observed in 1992; brant nested eight days later than in 1993, and number of nests in the area surveyed in both years was only 39% of what it was the following year.
The main cause of lower productivity in 1992 was that far fewer pairs nested that year (159 vs 514 in 1993, 69% lower) and, as summarized by Ganter and Boyd (2000) for other parts of the circumpolar region, this undoubtedly was caused by the almost two-week delay in snowmelt that occurred on Banks Island that year.
Eighteen of 27 marked females that nested on their capture/molt wetland were successful.
Although we did not know the exact age of the adult geese we marked, we knew they had nested as indicated by an incubation patch and cloacal characters (Hanson, 1959, 1965).
Although only nine geese nested on shorelines during our study, 78% of those nests hatched.
I used an unpaired t-test to test whether larger turtles nested more frequently per season than smaller turtles.
texana, 111 (82.8%) nested one time, 21 (15.7%) nested twice, and 2 (1.5%) nested three times.
scripta (78%) nested in short-grass areas devoid of cover.

Historically, Eastern White-winged Doves in Texas nested
primarily in native Tamaulipan brushlands of the Lower Rio Grande Valley (LRGV) from May through August and wintered in southwestern Mexico and Central America (George et al.
