Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops Fuscatus)
Adaptations of An Avian Supertramp: Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops fuscatus) Chapter 6: Survival and Dispersal The pearly-eyed thrasher has a wide geographical distribution, obtains regional and local abundance, and undergoes morphological plasticity on islands, especially at different elevations. It readily adapts to diverse habitats in noncompetitive situations. Its status as an avian supertramp becomes even more evident when one considers its proficiency in dispersing to and colonizing small, often sparsely The pearly-eye is a inhabited islands and disturbed habitats. long-lived species, Although rare in nature, an additional attribute of a supertramp would be a even for a tropical protracted lifetime once colonists become established. The pearly-eye possesses passerine. such an attribute. It is a long-lived species, even for a tropical passerine. This chapter treats adult thrasher survival, longevity, short- and long-range natal dispersal of the young, including the intrinsic and extrinsic characteristics of natal dispersers, and a comparison of the field techniques used in monitoring the spatiotemporal aspects of dispersal, e.g., observations, biotelemetry, and banding. Rounding out the chapter are some of the inherent and ecological factors influencing immature thrashers’ survival and dispersal, e.g., preferred habitat, diet, season, ectoparasites, and the effects of two major hurricanes, which resulted in food shortages following both disturbances. Annual Survival Rates (Rain-Forest Population) In the early 1990s, the tenet that tropical birds survive much longer than their north temperate counterparts, many of which are migratory, came into question (Karr et al. 1990). Whether or not the dogma can survive, however, awaits further empirical evidence from additional studies. -

Moreover, the Big Ideas of the Earth Science Literacy Initiative can be used within signage to address literacy. Because all citizens should have a basic knowledge of Earth Science in order to make informed decisions that relate to Earth Science, geotourism can be used as a way to increase Earth Science knowledge, along with other positive outcomes related to communities' increased well-being. -
Observations of Mixed-Species Bird Flocks at Kichwa Tembo Camp, Kenya
Observations of mixed-species bird flocks at Kichwa Tembo Camp, Kenya Alasdair I V Gordon and Nancy M Harrison Alasdair I V Gordon Anglia Ruskin University East Road Cambridge CB1 1PT UK e-mail: [email protected] Corresponding author and contact details: Nancy M Harrison Anglia Ruskin University East Road Cambridge CB1 1PT UK e-mail: [email protected] Telephone: 0845 196 2524 1 Abstract Mixed-species foraging flocks were studied at Kichwa Tembo Camp on the edge the Masia Mara National Reserve in Kenya between July and September 2004. Observations were made on 29 mixed-species flocks, in which 24 species participated. African Paradise Flycatcher Terpsiphone viridis , Black-backed Puffback Dryoscopus cubla , Grey-backed Cameroptera Camaroptera brachyura , Collard Sunbird Hedydipna collaris and Cabanis’s Greenbul Phyllastrephus cabanisi were the most common participants in mixed-species flocks, as well as among the most frequently encountered bird species overall. The Black-backed Puffback was identified as the nuclear species in flocks due to their abundance and frequency with which they were followed by other species. Mixed-species flocks represent another niche dimension in this diverse bird community, but few of these species could be described as flock specialists; most of the birds observed in mixed-species flocks in this study were opportunistic attendant species, including the African Pygmy Kingfisher Ispidina picta, not previously described as joining mixed-species flocks. 2 Introduction Mixed-species flocks of insectivorous birds are a conspicuous feature of tropical communities worldwide (Rand 1954, Moynihan 1960, Jones 1977, Powell 1979, Wiley 1980), important in structuring avian communities of African forests (Chapin 1932, Vernon 1980), but also evident in open woodland and savannah habitats (Greig- Smith 1978a, Thomson and Ferguson 2007). -
