Rock Pigeon (Columba livia) Science Article 2 abstract In domestic pigeons (Columba livia), the electrical activity of the major depressor muscle of the wing, the pectoralis (pars thoracicus), begins in late upstroke well before the wing begins its downstroke excursion. The two architecturally distinct heads of the pectoralis, the sternobrachialis and the thoracobrachialis, are differentially […]

THE PLAIN-BREASTED GROUND DOVEIN SURINAM
Plain-breasted Ground-Dove (Columbina minuta) Science Article 1 abstract The Plain-breasted Ground Dove (Columbina minuta minutu) is an extremely local bird in the coastal plain of Surinam (Haverschmidt, Birds of Surinam, p. 135, Oliver & Boyd, Edinburgh, 1968). I know of only one locality near Paramaribo where it is fairly numerous, and I have found it […]
Importance of Structural Stability to Success of Mourning Dove Nests
Mourning Dove (Zenaida macroura) Science Article 1 abstract Studies of nest-sites election and nesting habitats often involve a ‘characterization’ of nests and of habitats in which nests are found. Our objective in the present work is to identify nest-site characteristics that are associated with variation in components of Mourning Dove (Zenaida macroura) fitness( e.g. the […]
MULTIPLE BROODING AS A REPRODUCTIVE STRATEGY: TIME-CONSERVING ADAPTATIONS IN MOURNING DOVES
Mourning Dove (Zenaida macroura) Science Article 3 abstract The Mourning Dove (Zenaidam acroura) has a suite of adaptations that promotes multiple brooding, a common characteristic among columbids. Mourning Doves are well adapted for multiple brooding because they produce food (crop milk) for young nestlings in vivo and feed older nestlings a diverse granivorous diet. This […]
Radio-instrumented Mourning Dove Preyed Upon by Gray Rat Snake
Mourning Dove (Zenaida macroura) Science Article 2 abstract Several authors (George 1951, Balda 1965, Lesser 1966) have published accounts of avian predation on fledged Mourning Doves (Zenaida macroura). Additionally, Blair (1967) reported an unsuccessful attempt by a bullfrog (Rana catesbeianat)o capture a Mourning Dove in flight. To our knowledge, however, no report of reptilian predation […]
EFFECTS OF HEIGHT OF NEIGHBORING NESTS ON NEST PREDATION IN THE RUFOUS TURTLE-DOVE (STREPTOPELIA ORZENTALIS)
Oriental Turtle Dove (Streptopelia orientalis) Science Article 2 abstract In many bird species, nest predation is one of the most significant causes of breeding failure (Ricklefs 1969). Breeding density is often considered to affect nest predation. Higher breeding density often results in lower predation pressure for species which will mob nest predators (Berg et al. […]

The feeding from edge towards inner part in soybean plot in rufous turtle dove,Streptopellia orientalis (Latham) and the estimation of passing rate of the flock
Oriental Turtle Dove (Streptopelia orientalis) Science Article 1 abstract Rufous turtle dove,Streptopelia orientalis, coming to the soybean field entered it from the outer part to eat soybean cotyledons. As a result, the injured plants extended from the outer to inner parts in the field. A model expressing these behaviours was constructed here, by assuming that […]
Initial orientation in two species of doves (Streptopelia senegalensis and Turtur abyssinicus) displaced from their home site
Laughing Dove (Spilopelia senegalensis) Science Article 3 abstract The authors report data on initial orientation of laughing doves (Streptopelia senegalensis) and black-billed wood doves (Turtur abyssinicus) displaced to sites, on land and at sea, 1-40 km from their home ground which was near the coast, in the area of the ORSTOM Ornithological Station of Mbour, […]
Multiple nest use by the Laughing DoveStreptopelia senegalensis
Laughing Dove (Spilopelia senegalensis) Science Article 1 abstract Rowan (1983) made reference to multiple use of nests by the Laughing Dove: ‘
