Once located, nests were monitored every 3-5 days until young fledged or nests were depredated
If so, the costs must be capitalized and depredated
over the asset's useful life.
We recorded the location of all intact and depredated
nests found ([+ or -]3 m) using a Global Positioning System (GPS).
0 m; it is slightly eroded by waves and much depredated
Nests were considered depredated
if damage to nest construction and remnants of eggs, egg shells, and chicks were observed in or around nests.
Commercial Charter Recreational Islamorada 1 23 3 East Coast 17 12 2 Figure 3 Percent of surveyed fishermen identifying fish species that are depredated
by bottlenose dolphins (Tursiops truncatus) in the Florida king mackerel (Scomberomorus cavalla) fishery.
We hypothesized that nests located closer to well-traveled deer trails would be depredated
more often than those a greater distance from the trail.
We used a G-test of independence to test for significant heterogeneity between the proportion of experimental clutches depredated
in (a) urban and rural habitats, and (b) urban roofs with small pea gravel compared to those with larger river stone.
We considered a nest to be depredated
when the contents (eggs or nestlings) disappeared between two consecutive visits (Di Giacomo et al.
The focal nest contained six nestlings, which were captured at 16 days after hatching (21 May) for other studies as in the other 30 breeding nests (note that the remaining five nests were depredated
or at least disappeared before 16 days after hatching).
For nests depredated
during incubation, we estimated date of initiation as the midpoint between minimum and maximum possible dates of initiation.
Microhabitat features were similar for successful and unsuccessful nests, although successful nests were typically placed lower than depredated
To characterize nest loss, we calculated the proportion of nests parasitized by cuckoos and the proportion of nests lost (both abandoned and depredated
broods) for each reed habitat type relative to the total number of nests.
This simultaneous mobbing and intraspecific aggression shares similarities with the interaction described by Childs (1948), who reported that one towhee pair attacked another while both pairs attempted to drive off two western scrub-jays who had just depredated
In addition, we do not know if twinning occurred in any eggs depredated
prior to hatching.
