Detailing novel learn equipment, this compilation provides significant advances in basic facets of phylogeny, mating, parental care, the trophic constitution of Raptor groups, demography, behavioral ecology, species range, and the evolution of avian ontogenies. The booklet additionally positive factors the main broad record of foreign references to be had on raptor vitamin and feeding habit and nocturnality. Current Ornithology is the single English-language booklet presently committed solely to huge stories and synthesis of themes touching on all elements of the biology of birds. Chapters fall below such diversified rubrics as ecology, evolution, habit, phylogeny, behavioral ecology, anatomy and body structure, and conservation biology. All authors are prime experts on their topics, and every bankruptcy is refereed through specialists within the issues coated. even though all chapters concentration totally on birds, a few subject matters, equivalent to the social cognition of birds compared to primates (Volume 13), have major program to disciplines open air of ornithology. CurrentOrnithology goals to supply an available, up to date, exact resource of knowledge and to give a contribution to conceptual generalization and unification around the organic sciences.

Example text

At a proximate level these traits probably are controlled by endocrines, and the birds' inappropriate response reflects the lag time between a change in environmental conditions and the physiological response. At an ultimate level, the inability of a female Roadrunner to maintain a constant body temperature when forced to incubate at night, together with the metabolic pattern of the male deprived of its nest, suggest that nocturnal incubation by male Roadrunners and presumably other male cuckoos is a deeply rooted characteristic of this group, which could have prevented the evolution of polygynous mating systems in these birds.

However, breeding systems more complex than simple, single-pair monogamy have evolved in two North American species, the Red-cockaded (Picoides borealis) and Acorn (Melanerpes formicivorous) woodpeckers, both of which are categorized as cooperative breeders. However, in each of these species, as in other, more typical woodpeckers, nighttime incubation is conducted by the male parent and both sexes exhibit extensive care of eggs and nestlings. Thus their social-mating systems are extensions of, rather than departures from, the basic woodpecker pattern of parental care.

In short, what combination of factors led males of such species down the evolutionary pathway to the sole care of offspring? Although paternal care is almost the rule in birds, parental care solely by the male definitely is not. 2. The Distribution of Classical Polyandry Possibly the single most striking fact about classical polyandry is its taxonomic or phylogenetic distribution. It is restricted almost exclusively to five families in one order of birds, the Charadriiformes. , 1988; Sibley and Ahlquist, 1990) that traditionally has been placed in the Order Gruiformes.
