BAIT-FISHING BY STRIATED HERON — HAYES AND ROOKSobserved bait-fishing and have never observed itelsewhere. Second, many observations involve baitprovided by humans (e.g., bread), suggesting thathumans provided a model for herons which observedthat fish were attracted to bait. At the Pointe-a-PierreWildfowl Trust, Rooks has observed concentrationsof fish under the bird feeding stations waiting forcrumbs to fall and once noted humans compressing apiece of bread onto a fishing hook and line to baitfish. And third, several individuals are often involvedwhere bait-fishing occurs, suggesting culturaltransmission of information. We are uncertain, however,whether our observations include more thanone bird.In Japan, Higuchi (1986, 1988) reported that anadult Striated Heron was significantly more successfulforaging by bait-fishing than when other foragingtactics were used, that adults were more successfulbait-fishing than immatures, and that differences inthe proportion of time spent bait-fishing may be relatedto foraging habitat quality. Further quantitativestudies of bait-fishing in Butorides are needed to betterunderstand its adaptive significance.ACKNOWLEDGMENTSWe thank W. E. Davis, Jr., for reviewing themanuscript.

ADDITIONAL NOTES ON THE WINTERING STATUS OFSWAINSON’S WARBLER IN THE DOMINICAN REPUBLICCHRISTOPHER C. RIMMER 1 AND JESÚS ALMONTE 21 Vermont Institute of Natural Science, 27023 Church Hill Road, Woodstock, VT 05091, USA; and2 Fundación Moscoso Puello, Apartado Postal No. 1986, Zona 1, Santo Domingo, República DominicanaAbstract. – We report the third and fourth records of Swainson’s Warbler (Limnothlypis swainsonii)from Hispaniola. All four records have involved mist-netted birds in montane broadleaf forests of Sierrade Bahoruco in the Dominican Republic. The species has never been recorded during extensive ornithologicalfield studies in a variety of shrub-scrub and forested habitats elsewhere in the country. AlthoughSwainson’s Warblers use a range of habitats on other Greater Antillean islands, we believe that the species’Hispaniolan distribution may be largely or exclusively confined to high elevation broadleaf forests.We further believe that Swainson’s Warbler should be considered a regular, if local and uncommon, winterresident in the Dominican Republic. We encourage focused investigations, using tape-recorded playbacksand mist-netting, of the distribution and habitat associations of this species in other regions of Hispaniola.Resumen. – NOTAS ADICIONALES SOBRE EL ESTADO DE RESIDENCIA INVERNAL DE LA CIGÜITA DESWAINSON EN LA REPÚBLICA DOMINICANA. Reportamos el tercer y cuarto registro de la Cigüita de Swainson(Limnothlypis swainsonii) en La Española. Los cuatro registros han sido de aves capturadas en redesen el bosque montano latifolio de la sierra de Bahoruco en la República Dominicana. La especie nunca hasido observada durante investigaciones ornitológicas extensas efectuadas en diversos hábitats arbustivos yboscosos en otras partes del país. Aunque la Cigüita de Swainson ocupa una variedad de hábitats en otrasislas de las Antillas Mayores, creemos que la distribución de la especie en La Española podría estar principalmenteo exclusivamente limitada a los bosques latifolios a gran elevación. Además, creemos que en laRepública Dominicana la Cigüita de Swainson debería ser considerada como un residente invernal de ocurrenciahabitual, aunque local y rara. Alentamos las investigaciones enfocadas en la distribución y la asociaciónde hábitats de esta especie en otras regiones de La Española usando grabaciones y redes.Key words: distribution, Dominican Republic, habitat use, Limnothlypis swainsonii, montane forests,Swainson’s WarblerTHE RECENT DOCUMENTATION of within- and between-wintersite fidelity of Swainson’s Warbler(Limnothlypis swainsonii) in montane broadleaf forestsof the southwestern Dominican Republic suggeststhat the species may regularly overwinter onHispaniola (Rimmer and McFarland 1998, Rimmerand Tietz 2000). We report here the third and fourthrecords of Swainson’s Warbler from Sierra de Bahoruco,further supporting the species’ status as a regular,if uncommon, winter resident in this mountainrange. We captured unbanded Swainson’s Warblersat “Estacion Pueblo Viejo” in Parque Nacional Sierrade Bahoruco, Pedernales Province (18 o 20´ N, 71 o52´ W, ca. 1400 m elevation) on 25 January 2000and 31 January 2001. Pueblo Viejo is 2.6 km southeastof “Palo de Agua,” the site of the two previouslyreported mist-netted birds. Habitats at both sites areclassified as “premontane wet forest” (Fisher-Meerow and Judd 1989), which is characterized by adense understory of shrubs and vines and a solid canopyof broadleaf trees 8-15 m high. All four Swainson’sWarblers at the two sites were captured in microhabitatsof very high understory stem density.Although Swainson’s Warbler has only recentlybeen documented to occur on Hispaniola and is consideredan “accidental visitor” (Keith et al., in prep.),our banding records from Sierra de Bahoruco showthe species to be fifth in relative abundance amongthe eight species of North American migrants that wehave mist-netted in high elevation forests since 1995.Surprisingly, Swainson’s Warbler appears to bemore abundant in montane broadleaf forests of Sierrade Bahoruco than the ecologically similar WormeatingWarbler (Helmitheros vermivorus), of whichwe have captured only one individual in nearly10,000 hours of mist-netting since 1995. These twospecies co-occur in forested habitats on Jamaica(Graves 1996) and Cuba (Kirkconnell et al. 1996),and Worm-eating Warblers are uncommon but regularthroughout the Dominican Republic, inhabitingEl Pitirre 14(1) Page 5
