Phylogeny of the cuckoo genus Coccyzus(Aves: Cuculidae): a test of monophyly
Dark-billed Cuckoo (Coccyzus melacoryphus) Science Article 1 abstract Coccyzus comprises nine species of New World cuckoos (Aves: Cuculidae)that breed from southern Canada to central South America. The phylogeny of thisgenus was reconstructed using 2490 base pairs of the mitochondrial genes cytochromeoxidase II and III, and cytochrome b. Maximum likelihood, maximum parsimony,and Bayesian inference approaches produced […]

Foraging and diet composition of the black-capped foliage-gleaner (philydor atricapillus)
Black-capped Foliage-gleaner (Philydor atricapillus) Science Article 1 abstract Twenty nine samples regurgitated from the dead-leaf specialist Black-capped Foliage-gleaner (Philydor atricapillus) after administration of tartar emetic were examined to assess the diet of the species. Similarly, samples of invertebrate fauna living in suspended dead-leaf clusters were obtained to estimate prey availability for the birds. Diet was […]

Notes on the foraging behavior of the Zigzag Heron.
Zigzag Heron (Zebrilus undulatus) Science Article 4 abstract The only recent field observations reported for the poorly known Zigzag Heron (Zebrilus undulutus) (Hancock and Kushlan, Herons Handbook, Croom Helm, London, 1984) are those of Davis et al. (Condor 82:460-46 1, 198 1). Here we report on a bird watched intermittently by NJCM for about 13 […]

We therefore present our observations of an individual of this species and summarize several […]
