“…After examining census records for 79 other inland colonies throughout peninsular Florida, they found only 30% to be active for five or more years. More recently, Bryan et al (2003) calculated an annual turnover rate of 33% for nesting colonies in St. Johns River Basin. Over the length of their eight-year study the colony turnover rate was 72%.…”

To assess the ecological risk of siting a new municipal solid waste landfill near a National Wildlife Refuge in Florida, we carried out a retrospective assessment at a large waterbird colony located near an existing active landfill. Monitoring data collected over twenty years, including flight-line counts both at dawn and midday, shows the mixed-species, communal roost was active continuously from 1987 through 2007. The largest number of birds counted in any single flight-line count was 14,750 birds recorded in July 2007. The numerically dominant species recorded during flight-line counts were, in approximate order of abundance: White Ibis, (Eudocimus albus), Cattle Egret (Bubulcus ibis), Little Blue Heron (Egretta caerules), Great Egret (Ardea alba), and Tricolor Heron (E. tricolor). Breeding bird censuses revealed this site served also as a nesting colony each year since 1987; annual total nest numbers peaked in 1987 at 5,127 nests. Taxa richness increased over the monitoring period with new species nesting or roosting in the colony; in particular, the endangered Wood Stork (Mycteria americana) began nesting at this site in 1995 and eventually became one of the numerically important species.Nest success at the landfill colony was similar to or higher than success probabilities reported at other colonies in south Florida. Fidelity to this colony site was likely related to the area's environmental predictability in terms of: 1) food supply and, 2) the low, temporally constant level of predation. In general, resident waterbird populations at the colony were sustainable over the monitoring period, i.e., maintained abundance, survived and reproduced at rates comparable to other colonies. Therefore, although there was evidence of organism-level impacts, there was no evidence that landfill-related stresses propagated up and had population-or community-level consequences.

“…Proximity to water has been established as an important factor in the formation of all heron and egret colony types, including upland colonies (Dusi and Dusi 1968;Ogden et al 1980;Bancroft et al 1988;Bryan et al 2003). Normally upland colonies are within sight of water or have small water bodies adjacent to the nesting substrate (Dusi et al 1971;pers.…”

“…Whitfield & Blaber 1978). Other variables such as vegetation and land use around reservoirs and water quality of reservoirs also potentially affect waterfowl abundance (Johnsgard 1956, Bryan et al 2003. In this study, we will focus on the ecological function of shallow areas within water reservoirs for the abundance and diversity of waterfowl species.…”
