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 […]

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,
Heritability of wing length and weight in european bee-eaters (merops apiaster)
European Bee-eater (Merops apiaster) Science Article 2 abstract […]. Here we report repeatability and heritability values for wing length and weight in the European Bee-Eater, Merops apiaster. […]. C. M. Lessels and G. N. Ovenden, The Condor 91:21C-214 Download article download full text (pdf)
A Case of Bigamy in the European Bee-eater (Merops apiaster)
European Bee-eater (Merops apiaster) Science Article 1 abstract This example of bigamy is interesting, because it does not fit with current hypotheses about the adaptive value of polygyny. Orians (1969) argued that females may sometimes gain by being the second female on a good territory rather than a lone female on a poor territory, and […]
Age and breeding performance of European Bee-eaters
European Bee-eater (Merops apiaster) Science Article 5 abstract We studied breeding biology of the European Bee-eater (Merops apiaster) at a colony in southern France from 1983 to 1987. Approximately 50% of the breeding birds were juveniles (hatched the previous calendar year), and ca. 34% of the breeding birds in any year were known to return […]
Helping at the nest in European Bee-eaters: Who helps and why?
European Bee-eater (Merops apiaster) Science Article 6 abstract Avian cooperative breeding has been regarded as an ideal system in which to investigate the role of kin selection in the evolution of altruistic behaviour (Brown 1987). However, many studies of helping at the nest have been carried out on communally breeding species in which the costs […]
Nesting of European bee-eaters (Merops apiaster)in Central Europe depends on the soil characteristicsof nest sites
European Bee-eater (Merops apiaster) Science Article 4 abstract The European bee-eater (Merops apiaster) is the rst known species of theorder Coraciiformes and the second bird species whose distribution dependson the granulometrical characteristics of soils constituting suitable banks forbreeding. The mean particle size of soil samples from bee-eater nest placeswas 42.76 13.58 m (max 66.82 […]
The European bee-eater (Merops apiaster) as anecosystem engineer in arid environments
European Bee-eater (Merops apiaster) Science Article 3 abstract Arid environments are fragile ecosystems where management is particularly complicated.Determining target species that contribute to understanding the functioning of suchenvironments is of basic importance. Here we assess the role of the European bee-eater, aburrow-nesting bird species, as an ecosystem engineer in arid ecosystems. We concludethat this species […]
Behavior and energy budgets of Belted Kingfishers in winter
Belted Kingfisher (Ceryle alcyon) Science Article 2 abstract I recorded behaviors and estimated energy intake and expenditures of 16 Belted Kingfishers (Ceryle alcyon) during January and February 1994. Each bird was watched for an entire day to examine the relationships among temperature, time of day, and foraging behavior. Estimates of total daily energy intake and […]
Territory size in Megaceryle alcyon along a stream habitat
Belted Kingfisher (Ceryle alcyon) Science Article 1 abstract Belted Kingfishers (Megaceryle alcyon) defend both breeding and nonbreeding territories. The small nonbreeding territories serve as feeding territories, and their size is inversely correlated to food abundance. In the breeding season, when nest sites are a limiting resource, territory size does not significantly correlate with food abundance. […]
