Great Kiskadee (Pitangus sulphuratus) Science Article 3 abstract The Great Kiskadee (Pitangus sulphuratus) is one of the commonest and most conspicuous bird species in Paraguay (del Castillo & Clay 2004, Smith & Clay in press) and is well known for its robust and rowdy nature. During fieldwork at Estancia Laguna Blanca, Departamento de San Pedro, […]
Reed die-back, water level management and the decline of the Great Reed Warbler Acrocephalus arundinaceus in The Netherlands.
Great Reed-Warbler (Acrocephalus arundinaceus) Science Article 4 abstract Several species of migratory marsh birds have declined in Central and Western Europe. An important question is whether this decline is primarily caused by loss of wetlands on the wintering grounds in Africa or by a decline in habitat quality in the breeding areas. Significant losses of […]
The study of bird migration across the WesternSahara; a contribution with sound luring
Grasshopper-Warbler (Locustella naevia) Science Article 1 abstract During spring and autumn migration 2003, the Swiss Ornithological Institute set up a concerted project in Mauritania to study bird migration across the Sahara. I participated with a side project using artificial induction of landfall with sound luring in an attempt to overcome the potential problem of low […]
Grasshopper Warbler Locustella naevia autumn migration-findings from a study in southeast Britain
Grasshopper-Warbler (Locustella naevia) Science Article 2 abstract This study examines the migratory behaviour of Grasshopper Warblers Locustella naevia on the south coast of Britain with respect to phenology, fuel loads, stopover behaviour and potential flight ranges. Data were derived from 5,455 mist-net captures gathered over 10 years between July and October at the Pannel Valley […]

BEHAVIOR OF THE GRASSLAND SPARROW AND TWO SPECIES OF SEED-FINCHES
Grassland Sparrow (Ammodramus humeralis) Science Article 1 abstract The behavior of many of the predominantly granivorous neotropical bird species cOnventionally grouped under the familial heading Fringillidae in field guides is poorly known. Documenting it may help promote a better understanding of the phylogeny and Systematics of these birds and clarify the evolution and adaptive significance […]
THE SONG OF THE FOX SPARROW
Fox Sparrow (Passerella iliaca) Science Article 2 abstract The study of the song of the fox sparrow is a highly tantalizing pursuit owing to the bird’s brief stay, provoking habits of silence and reluctance to sing in full voice.

Changes in body condition from spring migration to reproduction in the Garden Warbler Sylvia borin : a comparison of a lowland and a mountain population
Garden Warbler (Sylvia borin) Science Article 1 abstract Long-distance migrants often arrive on their breeding grounds with large fat stores . Two expl anations for this phenomenon are (1) that large fat stores at arrival are needed to speed up the breeding schedule and to counteract possible time constraints, and (2) that they are used […]
