“…The range-high number of nestlings fledged per successful target nest (mean ϭ 3.2, SE ϭ 0.03, n ϭ 18 nests) was greater than the number fledged per successful reference nest (mean ϭ 2.5, SE ϭ 0.25, n ϭ 11 nests), a difference that was significant (t ϭ 2.8, df ϭ 27, p ϭ 0.0098) but opposite that which would be predicted if PCBs were assumed to impair nestling survival. Fledging success of target nestlings (mean ϭ 98%, SE ϭ 1.83%, n ϭ 18 nests) and 35,36] reference nestlings (mean ϭ 91%, SE ϭ 6.51%, n ϭ 11 nests) was not significantly different (t ϭ Ϫ1.3, df ϭ 27, p ϭ 0.20). Bioequivalence testing [27] was employed to determine whether any potentially biologically relevant differences existed in numbers of nestlings hatched and fledged, hatching success, and fledging success between the target and the reference populations ( Table 1).…”

“…We also tended to find cardinal nests earlier at urban sites, with nesting typically initiating a week and a half before rural sites (D. Burhans, personal observation). Other studies in urban or suburban locations have found that urban populations may enjoy longer breeding seasons (Morneau et al 1995 and references therein), perhaps because of greater warmth in urban areas.…”

“…For example, studies have shown that, although birds may use forest fragments, they may not be reproducing at sustainable levels in them (Robinson et al 1995; thus, presence of the birds alone does not provide insights into habitat quality or into the forces driving species abundance (Marzluff et al 2001). A number of studies have examined nesting in urban habitats, but these have typically either been single-species studies (Morneau et al 1995) or nonreplicated multi-species studies (Weber 1975). Artificial-nest studies have been used to compare nesting success between anthropogenic and natural settings (Melampy et al 1999, Miller andHobbs 2000), but recent work shows that artificial nests experience different predation rates than real nests (Burke et al 2004) and that different predators are attracted to real and artificial nests (Thompson and Burhans 2004).…”

“…Model simulations for all four sites used parameter values and sampling ranges derived from published values [22][23][24][25][26][27][28][29][30][31][32][33] (table 1). Further information on model assumptions are described in the electronic supplementary material.…”
