Nuevos registros y actualizacion de la distribucion de la Candelita Americana (Setophaga
ruticilla) en el Peru.
In 2017, we processed 39 birds: 11 American robins (Turdus migratorius), 1 common yellowthroat (Geothlypis trichas), 20 gray catbirds (Dumetella carolinensis), 2 house wrens (Troglodytes aedon), 1 indigo bunting (Passerina cyanea), 3 northern cardinals (Cardinalis cardinalis), and 1 American yellow warbler (Setophaga
Only two migratory species were recorded in the study area (Setophaga
fusca and Cardellina canadensis).
We monitored 997 active nests of eight species with sufficient sample sizes to fit nest survival models including 73 Acadian flycatcher (Empidonax virescens, [n.sub.eff] = 1276), 172 bluegray gnatcatcher (Polioptila caerulea, [n.sub.eff] = 1980), 256 Eastern wood-pewee (Contofms virens, [n.sub.eff] = 5344), 72 field sparrow (Spizella pusilla, [n.sub.eff] = 608), 207 indigo bunting (Passerina cyanea, [n.sub.eff] = 2206), 47 prairie warbler (Setophaga
discolor, [n.sub.eff] = 504), 66 summer tanager (Piranga rubra, [n.sub.eff] = 893), and 102 yellow-breasted chat (Icteria virens, [n.sub.eff] = 1021) nests.
The long-term goal is to provide one-third of a mile of buffer on either side of the Patoka River to provide uninterrupted breeding and rearing habitat for interior nesting birds, such as the cerulean warbler (Setophaga
cerulea), endangered Indiana bat (Myotis sodalis) and the threatened northern long-eared bat (Myotis septentrionalis).
Este mismo tipo de vegetacion (BMM) presento el mayor numero de especies residentes (e.g., Amazona finschi, Columbina inca, Piranga bidentata) y el menor numero de especies migratorias (e.g., Geothlypis tolmiei, Parkesia motacilla, Setophaga
These observations included barred owl (Strix varia), peregrine falcon (Falco peregrinus), veery (Catharus fusceseens), American redstart (Setopliaga ruticilla), chestnut-sided warbler (Setophaga
pensylvanica), and black-throated green warbler (Setophaga
Another remarkable recovery story, and one of the most dramatic successes to emerge from the Class of '67, is that of the Kirtland's warbler (Setophaga
kirtlandii), a songbird that winters in the Bahamas and spends spring and summer months primarily in Michigan's northeastern Lower Peninsula.
GENOMIC VARIATION OF BREEDING META-POPULATIONS OF CERULEAN WARBLERS (SETOPHAGA
We found a very low level of cowbird parasitism on western woodpewees at our study site even though other species, such as yellow warblers (Setophaga
petechia) and warbling vireos (Vireo gilvus), experienced moderate to heavy parasitism at the same site (Ortega and Ortega, 2000, 2003a).
