A Broad-winged hawk, Buteo platypterus (Vieillot), was seen in 1995 in <strong>the</strong> oak-hickory forest<br />
in <strong>the</strong> vicinity <strong>of</strong> <strong>the</strong> National Cemetery (Freeman et al. 1997). This species was observed in<br />
2002–2003 in <strong>the</strong> same general vicinity (Figure 3.6). Nesting has not been confirmed but it is<br />
likely that a pair is nesting somewhere between <strong>the</strong> National Cemetery and Hancock Hill.<br />
The great egret, Ardea alba (Linnaeus), has nested at FLMR from about 1992 to at least 1996 in<br />
<strong>the</strong> large colony <strong>of</strong> great blue herons in <strong>the</strong> mature floodplain forest (Figure 3.6). However, none<br />
was observed in this study. This is a conspicuous bird, so it probably was not present <strong>the</strong>se two<br />
years, a fact perhaps related to drought conditions that may have reduced foraging habitat.<br />
Ovenbirds, Seiurus aurocapillus (Linnaeus) were recorded at two sites in upland forest in 1995–<br />
1996 (Figure 3.6). This large, ground-nesting warbler occurs most <strong>of</strong>ten in large tracts <strong>of</strong> dry,<br />
upland woods with abundant leaf litter. Ovenbirds were not observed in 2002–2003.<br />
Faunistic Surveys<br />
Herpetological Survey. A report on a survey <strong>of</strong> snakes on FLMR is presented in Appendix E.<br />
In addition to that survey, o<strong>the</strong>r records were ga<strong>the</strong>red <strong>of</strong> reptiles and amphibians encountered<br />
while conducting targeted surveys for protected species. Reptile and amphibian site locations are<br />
summarized in Figure 3.7. Most records are described in Appendix E.<br />
Floodplain Point Counts for Birds. Results <strong>of</strong> fixed-radius and unlimited-distance point counts<br />
for birds in three forest types (Figure 3.3) along a successional gradient are summarized in Table<br />
3.8. Species richness was highest in <strong>the</strong> old-growth forest (43 species, unlimited distance; 36<br />
species, fixed-radius), lowest in <strong>the</strong> mid-successional forest (36 species, unlimited distance; 29<br />
species, fixed-radius), and intermediate in <strong>the</strong> early successional forest. Species composition<br />
exhibited high overlap among forest types, but each forest type had some unique species or at<br />
least some species whose relative abundance varied markedly with forest type. Species recorded<br />
only in old-growth forest included <strong>the</strong> red-shouldered hawk, yellow-throated warbler, and parula<br />
warbler. Species more abundant in this forest type included <strong>the</strong> pileated woodpecker, Acadian<br />
flycatcher, Carolina wren, and wood thrush. As expected, most <strong>of</strong> <strong>the</strong>se birds prefer mature,<br />
closed-canopy forest. Species unique to early successional forest were open country or edgedwelling<br />
birds such as <strong>the</strong> nor<strong>the</strong>rn bobwhite, eastern kingbird, eastern bluebird, brown thrasher,<br />
yellow warbler, and orchard oriole. As expected from its intermediate successional condition, <strong>the</strong><br />
mid-successional forest had no species unique to it, and <strong>the</strong> relative abundance <strong>of</strong> most species<br />
was intermediate between <strong>the</strong> o<strong>the</strong>r two forest types. The only species that was markedly more<br />
common in mid-successional forest was warbling vireo, a species that prefers large cottonwoods.<br />
All three floodplain forest types support a relatively high diversity and density <strong>of</strong> breeding birds<br />
and contribute substantially to <strong>the</strong> native, avifaunal diversity <strong>of</strong> FLMR. However, it should be<br />
pointed out that <strong>the</strong> conservation status <strong>of</strong> different bird species does vary (Partners in Flight<br />
2003). Higher priority species in Bird Conservation Region 22 (Eastern Tallgrass Prairie) that<br />
are found in <strong>the</strong> FLMR floodplain forest include, from higher to lower scores, cerulean warbler,<br />
red-headed woodpecker, wood thrush, prothonotary warbler, Acadian flycatcher, orchard oriole,<br />
