Spring migration dates of teal Anas crecca ringed in theCamargue, southern France
Green-winged Teal (Anas carolinensis) Science Article 4 abstract The policy of the European Commission prohibits hunting of migratory birds while they travel to their breeding grounds. To date, spring migration dates of ducks have mainly been determined using bird counts, but the validity of this sometimes disputed method has never been tested. We used ring-recovery […]

Sexing juvenile Greenfinches Carduelis chloris by the extent of black on the tail
Greenfinch (Carduelis chloris) Science Article 2 abstract There is increasing interest in the study of the evolution of sex ratios in birds. Correct assignment of sex to fledgling and juvenile birds is critical for studies that deal with differential sex allocation at nests or sexual variation in survival or dispersion rates. Here we describe a […]
Structural conservation and variation in the mitochondrial control region of fringilline finches (Fringilla spp.) and the greenfinch (Carduelis chloris
Greenfinch (Carduelis chloris) Science Article 4 abstract We sequenced the entire control region and portions of flanking genes (tRNAPhe, tRNAGiu, and ND6) in the common chaffinch (Fringilla coelebs), blue chaffinch (F. teydea), brambling (F. montifringilla), and greenfinch (Carduelis chloris). In these finches the control region is similar in length (1,223-1,237 bp) and has the same […]
The removal of colour rings by Greenfinches Carduelis chloris
Greenfinch (Carduelis chloris) Science Article 3 abstract This paper examines the effect of sex and ring colour on the frequency of removal of plastic colour rings by Greenfinches Carduelis chloris. Of 55 recaptures of 42 individuals, 22 (40%) had lost at least one of its colour rings. Females showed a tendency to remove colour rings […]
Activity and predator escape performance of common greenfinches Carduelis chloris infected with sindbis virus
Greenfinch (Carduelis chloris) Science Article 1 abstract The fitness effects of parasites on their hosts are often unknown. For mostavian viruses, no records of clinical disease have been associated withinfections. In this study we tested if birds would alter their behaviour duringan infection with an avian virus that naturally occurs in passerines. Wemeasured spontaneous locomotion […]
The Relation of Hunting Site Changes to Hunting Success in Green Herons and Green Kingfishers
Green Kingfisher (Chloroceryle americana) Science Article 2 abstract Considerable information is available on the feeding habits of herons and kingfishers (e.g., Skutch 1957; 1972. Meverriecks 1960. 1966. 1971. Slud 1964. Ienni 1969: Recher and Rechkr 1972, Kushlan 1973,
THE GREEN KINGFISHER
Green Kingfisher (Chloroceryle americana) Science Article 1 abstract Green Kingfisher (Chloroceryle americana) inhabits watercourses and shores from southern Texas and Arizona to the northern tributaries of Hudson’s La Plata, from the brackish water of mangrove-fringed lagoons to mountain streams 7000 feet above the sea. The two extremes of habitat are the exception, however; it prefers […]
FORAGING ECOLOGY OF SEVEN SPECIES OF NEOTROPICAL IBISES (THRESKIORNITHIDae) DURING THE DRY SEASON IN THE LLANOS OF VENEZUELA
Green Ibis (Mesembrinibis cayennensis) Science Article 1 abstract sympatric species of ibises (Threskiomithidae) in the Venezuelan llanos during the dry season of 1989. Scarlet (Eudocimus ruber), Glossy (Plegadis falcinellus), and Bare-faced (Phimosus infiscatus) ibises were the most common species. White (E. albus), Green (Mesembrinibis cayennensis), Sharp-tailed (Cercibis oxycerca), and Buff-necked( Theristicus caudatus) ibises together made […]
