Research papers on brood parasitism

Advances in the study of coevolution between avian brood parasites and their hosts annual review of ecology, evolution, and systematics vol 45:227-246 ( volume publication date november 2014) first published online as a review in advance on september 25, 2014 https://doiorg/101146/annurev-ecolsys- 120213-. She does her field research in zambia, home to 31 species of brood parasites spottiswoode says there her team published a paper last year that showed that female cuckoo finches go undercover as harmless southern red bishops to fool their host, the tawny-flanked prinia (they often foil birders, too. The warblers accepted brood parasitism and did not choose nest sites inaccessible to cowbirds, defend nests during the egg-laying period, desert parasitized nests, or avoid returning to sites where they had been parasitized the results of this research indicate that these birds may be able to avoid chronically high rates of. Surprisingly the de groot and smith (2001) study is the first to assess whether this brood parasite can change bird community composition they state their hypothesis as: this work has management implications in regard to cowbird removal programs designed to protect endangered birds de groot and smith worked in. This study investigates for the first time the occurrence of conspecific brood parasitism (cbp) in sympatric tropical populations of the common moorhen ( gallinula chloropus pauxilla bangs) and the american purple gallinule ( porphyrula martinica l) cbp occurred in at least 20% (n = 76) of common moorhen nests on the. Conspecific brood parasitism (cbp) occurs in various insects, fishes and birds, but it is disproportionately common in waterfowl (anatidae) studies of cbp in anatids therefore have helped to develop a fundamental conceptual framework with which to explain this intriguing behaviour yom-tov (1980) first.

I will deal with the issue using the studies of the well known brood parasite, the common cuckoo (cuculus canorus hereafter “cuckoo”), to illus- trate the magnitude of the issue research: number and sample sizes of egg vs chick studies an overview of brood parasitism papers on the cuckoo included in. How human activity influences risk of nest predation and brood parasitism at key words: brood parasitism, cuckoo, nest predation, human disturbance, human throughout the work especially, i would like to thank dr bård gunnar stokke who always encourages me to work hard in the field this research would not be. Research papers egg coloration and recognition of conspecific brood parasitism in eastern bluebirds lynn siefferman department of biological sciences, auburn university, al, usa introduction conspecific brood parasitism , whereby females lay eggs in the nests of conspecifics but provide no care.

(physorg) —a team of researchers in spain has found that at least one species of cuckoo bird may actually help its nest-mates survive in their paper avian brood parasites lay eggs in the nests of other birds, which raise the unrelated chicks and typically suffer partial or complete loss of their own brood. Main themes and results of mélanie guigueno's past and present research we also describe our work on cognition in brood parasites in an upcoming book chapter, hippocampus and spatial memory in brood parasitic cowbirds to be published in avian brood parasitism - behaviour, ecology, evolution and coevolution.

Interspecific brood parasitism has evolved independently in several avian lineages, including cowbirds (molothrus sp) which occur throughout the americas we work in close collaboration with members of the ecology and animal behaviour lab (laboratorio de ecologia y comportamiento animal, prof juan carlos. Conceptually, our past and current work on brood parasitic birds aims to help answer three general questions: first, how do interactions between species generate diversity among individuals we are interested in how biological arms races between hosts and parasites shape phenotypic diversity in both parties. Rather than being a rare and intriguing system to study coevolutionary processes , i believe that avian brood parasites and their hosts are much more an optimality approach can be applied to work out a threshold frequency of brood parasitism above which egg rejection results in higher reproductive success and below.

  • Robins are a suitable study species in that they are one of fewer than 30 documented cowbird host species to eject cowbird eggs at rates above 75% ( briskie et al, 1992 peer and sealy, 2004), allowing for the testing of specific sensory hypotheses mediating egg rejection in this system previous work on this species pair.
  • Our work with reed warblers and cuckoos in the uk shows that hosts use both personal and social information to fine-tune their behaviour (see here and here), and the way they use social information has consequences for cuckoos as reed warblers pay attention to the specifics of the information provided when neighbours.

We present data on the brood-parasitic behavior of the pavonine cuckoo ( dromococcyx pavoninus) in 3 host species of small-bodied flycatchers in the peruvian amazon that construct hanging globular nests with side entrances during the 7 yr of the study, we encountered 74 nests of these 3 hosts, but parasitism occurred. Brood parasites are birds that lay their eggs in the nests of other species (the hosts), and have their offspring raised by the host parents in some parasitic species (such as the common cuckoo cuculus canorus) the newly hatched chick expels all other eggs and chicks from the nest and so avoids competition for food. Abstract red-winged blackbirds (agelaius phoeniceus) are a polygynous songbird with facultative biparental care, and a common host for brown-headed cowbirds (molothrus ater), an obligate brood parasite we examined brood parasitism and paternal care in a long-term study of parental care in.
