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 />
