In five nests in our study, I mexicana cells were situated outside of partial or complete leafcutting bee cells (Megachilidae: Megachile sp., probably Megachile relativa Cresson which
nested at these sites), and all five nests were closed with an I.
Least terns
nested at the ash ponds and the landfill from 6 June through 24 July.
When nest height was
nested within taxonomic family, nest predation differed among nest heights (F = 6.9, P = 0.003, n = 35) in a parabolic relationship [ILLUSTRATION FOR FIGURE 1A OMITTED], where shrub nests had greater nest predation than both ground and canopy nests and canopy nests had greater nest predation than ground nests (P [less than] 0.05, Duncan's test).
This suggests that Mandarin ducks may usurp occupied boxes in which they had
nested previously.
A Carolina Chickadee (Poecile carolinensis) pair
nested unsuccessfully.
Among colonies with nests on more than one island, most brant
nested on one island, with the remaining pair(s) usually nesting alone (rarely [greater than or equal to] 2 pairs) on a smaller nearby island.
The segments remind Ward of the
nested tubes of a telescope.
fisheri (Louisiana seaside sparrow)
nested in mangroves, neither constructed canopied nests (Bent, 1968).
Forest patches in which turkeys
nested were relatively large (mean patch size = 424 ha) and provided ample nesting availability further from edge areas.
Last year only 10 pairs of hen harriers successfully
nested in England, and a team of RSPB nest protection wardens are now on standby to start a 24-hour watch on the nest site should the birds breed.
Although riparian forests comprised 36.0% of the area, no hens
nested in that habitat ([chi square] = 52.23, 3 df, P = 0.001).
When sparrows
nested in gull neighborhoods, the sparrows were "unusually wary in approaching their nests," which they kept well hidden in patches of blueberry and goldenrod.
Stilts typically
nested in more vegetation than avocets, which may have reduced predation by visual avian predators; however, the difference in composition of predator faunas between nests of avocets and stilts was likely an artifact of size of sample.
For geese that
nested on wetlands other than where they were captured, we recorded the date they returned to their capture wetland.
Wood ducks
nested in boxes along the Canadian and Washita rivers.
