Based on several lines of evidence, a specimen of an adult white-morph Reddish Egret (Egretta rufescens) now on display in the Macdonald Museum of the Annapolis Valley Historical Society in Middleton, Nova Scotia, probably originated from the 19th-century Nova Scotian bird collections of Thomas McCulloch senior (1776–1843) and his son Thomas (1809–1865), likely between 1838 and 1865. The only other records of this species in Canada are sightings in Nova Scotia in 1965 and 1966. This may therefore be the first specimen evidence of the species in Nova Scotia and Canada. Historical evidence links the specimen with the McCulloch collection of birds, part of which has survived at Dalhousie University.

Egretta Rufescens

It has been hypothesized that white plumage facilitates flock formation in Ardeidae. We conducted four experiments using decoys to test factors involved in attracting wading birds to a specific pond. The first three experiments tested the effects of plumage colouration, flock size, and species-specific decoys on flock formation. The fourth experiment examined intraspecific differences in flock choice between the two colour morphs of the reddish egret, Egretta rufescens (Gmelin, 1789). Wading birds landed at flocks of decoys more often than single or no decoys (P < 0.001) but exhibited no overall attraction to white plumage (P > 0.05). White-plumaged species were attracted to white decoys (P < 0.001) and dark-plumaged species were attracted to dark decoys (P < 0.001). Snowy egrets (E. thula (Molina, 1782)), great egrets (Ardea alba L., 1758), and little blue herons (E. caerulea (L., 1758)) landed more often at ponds that contained decoys resembling conspecifics. At the intraspecific level, all observed reddish egrets selected flocks with like-plumaged decoys. Our results suggest that plumage colouration is an attractant for species with similar plumage, but white plumage is not an attractant for all wading bird species. White plumage may facilitate flock formation in certain species but does not serve as a universal attractant for wading birds of varying plumage colouration and size.

Presentamos los registros de aves enviados al Comité Ecuatoriano de Registros Ornitológicos (CERO) entre Julio 2013 y Marzo 2014. CERO recopila la lista oficial de aves del Ecuador y la actualiza anualmente. Presentamos cuatro registros nuevos para el país (Amazonetta brasiliensis, Porzana albicollis, Haematopus ater, Chroicocephalus Philadelphia), un registro nuevo que antecede a otros previamente publicados (Vireo flavifrons), la primera documentación en el país de cuatro especies (Larus californicus, Tangara guttata, Conirostrum bicolor, Cardellina pusilla) y 26 extensiones significativas de distribución o registro de especies raras (Oceanodroma leucorhoa, Oceanodroma hombyi, Sula leucogaster, Phalacrocorax bougainvillii, Butorides virescens, Ardea herodias, Egretta rufescens, Egretta caerulea, Eudocimus albus, Eudocimus ruber, Anas clypeata, Anas cyanoptera, Aythya qffinis, Gallinago delicata, Limosa fedoa, Larus delawarensis, Hydroprogne caspia, Glaucidium griseiceps, Chloroceryle aenea, Platyrinchus saturatus, Myiarchus crinitus, Tyrannus niveigularis, Knipolegus poecilurus, Doliomis remseni, Setophaga castanea, Lonchura malacca). Tres registros provienen de las islas Galápagos (Oceanodroma leucorhoa, Butorides virescens, Egretta caerulea), mientras que todos los demás provienen del Ecuador continental. Se eliminan seis especies del listado nacional (Geotrygon violácea, Topaza pella, Attila bolivianas, Pachyramphus rufus, Pachyramphus validus, Lonchura atricapilla). Dos registros adicionales se pospusieron para revisiones más detalladas (Thalassarche cauta) o evidencias adicionales (Neomorphus pucheranit) y se rechazan los reportes de tres especies (Patagioenas oenops, Hydropsalis maculicaudus, Colaptes rupicola). Esta información actualiza nuestro conocimiento sobre la distribución y estado de especies de aves poco conocidas en Ecuador, asi como el listado nacional de aves que actualmente incluye 1673 especies (1608 confirmadas y documentadas, 65 hipotéticas).
