Smooth-billed Ani (Crotophaga ani L.), a New Species of Bird for Ohio

Smooth-billed Ani (Crotophaga ani) Science Article 2 abstract A smooth-billed ani (Crotophaga ani L.) is reported from Ohio for the first time. The specimen(CMNH 68471) also represents the first inland state record for the United States. Confirmation of specificidentity was obtained because of the significance of the record and some equivocal characteristics of thespecimen. Care […]

Phylogeny of the cuckoo genus Coccyzus(Aves: Cuculidae): a test of monophyly

Pearly-breasted Cuckoo (Coccyzus euleri) 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 […]

Do Common Whitethroats (Sylvia communis) discriminateagainst alien eggs?

Cuckoo (Cuculus canorus) Science Article 2 abstract In a coevolutionary arms race between a brood parasite and its host, both species are expected to evolve adaptations and counteradaptations, such as egg mimicry and egg discrimination. The Common Whitethroat (Syh, ia communis) is a regular Common Cuckoo (Cuculus canorus) host in some parts of its breeding […]

Rejection of cuckoo Cuculus canorus eggs in relation to female age in the bluethroat Luscinia svecica

Cuckoo (Cuculus canorus) Science Article 1 abstract The evolutionary equilibrium hypothesis explains the existence of both acceptors and rejecters of brood parasite eggs within a host population as resulting from a balance between the costs of acceptance and the costs of recognition errors. In such equilibria conditional responses may play an important role. One such […]

The evolution of egg rejection by cuckoohosts in Australia and Europe

Cuckoo (Cuculus canorus) Science Article 3 abstract Exploitation of hosts by brood parasitic cuckoos is expected to stimulate a coevolutionary arms race of adaptations andcounteradaptations. However, some hosts have not evolved defenses against parasitism. One hypothesis to explain a lack of hostdefenses is that the life-history strategies of some hosts reduce the cost of parasitism […]

Young Cuckoo (Cuculus canorus) in the nest of the Black Redstart (Phoenicurus ochruros)

Cuckoo (Cuculus canorus) Science Article 4 abstract I found a young cuckoo (Cuculus canorus) in the nest of the black redstart (Phoenicurus ochruros) in the viticultural area of Andra{evec (46 deg 00’N, 15 deg 57’E), in north-western Croatia, on June 15, 2004. The nest was situated on an outer wooden beam of a building in […]

How are different Common Cuckoo Cuculus canorus egg morphs maintained? An evaluation of different hypotheses

Cuckoo (Cuculus canorus) Science Article 5 abstract The aim of this study was to investigate the occurrence of Common Cuckoo Cuculus canorus egg morphs in relation to host species and nest sites. The study is based on analyses of museum egg collections and field observations of Common Cuckoo parasitism in three regions of the Czech […]

Erect Posture of the Young Black-billed Cuckoo: An Adaptation for Early Mobility in a Nomadic Species

Black-billed Cuckoo (Coccyzus erythropthalmus) Science Article 2 abstract The vertical or perpendicular pose of the young Black-billed Cuckoo (Coccyzuse rythropthalmush) as been suggestedto function in concealing the young, implicitly from predators (e.g. Herrick 1910, Bent 1940). F. H. Kennard (in Bent 1940: 75-76) gives thefollowing description of a young Black-billed Cuckoo in this pose SPENCER […]

EXTERNAL DIFFERENCES BETWEEN NEWLY HATCHED CUCKOOS (COCCYZUS AMERICANUS AND C. ERYTHROPTHALMUS

Black-billed Cuckoo (Coccyzus erythropthalmus) Science Article 3 abstract Yellow-billed Cuckoos (Coccyzus americanus) and Black-billed Cuckoos (C. erythropthalmus), although nonparasitic, do from time to time lay their eggs in the nests of each other and of various passerines VAL NOLAN, JR., Condor(77)3:341 Download article download full text (pdf)
