The West Indies host a diverse community of raptors whose origins can be
traced to North, Central, and South America. In the region, 37 raptor species have been
reported, 27 of which are diurnal (Cathartidae, Accipitridae, and Falconidae) and 10 are
nocturnal (Tytonidae and Strigidae). Nine species are regional endemics, 6 are non-endemic permanent...
I describe a White-banded Swallow (Atticora fasciata) diving under water to avoid predation by a Bat Falcon (Falco rufigularis) in Madre de Dios River, Peru. On 3 September 2006 I observed a White-banded Swallow plunge-diving under water for a distance of ∼30 cm (6 times) with ∼1 m flights close to the water surface in between (5 times) before reac...
Reliable estimates of life history parameters and their functional role in animal population trajectories are critical, yet often missing, components in conservation and management. We developed seasonal matrix population models of the Red‐tailed Hawk in the upper and lower forests of the Luquillo Mountains, Puerto Rico, to describe the influence o...
Reliable estimates of species abundance, distribution, and population trajectories
are critical in conservation and management. However, for many tropical species that
information is missing. We conducted Sharp-shinned Hawk (SSHA) searches during the
breeding seasons of 2013, 2014, and 2016 in eight montane forest reserves and their
adjacent privat...
en Sharp‐shinned Hawks (Accipiter striatus) are forest raptors that are widely distributed in the Americas. A subspecies endemic to Puerto Rico (A. s. venator) is listed as endangered and restricted to mature and old secondary montane forests and shade coffee plantations. However, recent information about the population status and distribution of P...
Hispaniola is the second largest island in the Caribbean that includes the countries of Dominican Republic and Haiti and has five resident owl species inhabiting open landscapes, rainforests, human-modified areas, and cities. The five species are the barn owl (Tyto alba), the endemic ashy-faced owl (T. glaucops), burrowing owl (Athene cunicularia),...
Eggs from aplomado falcons (Falco femoralis septentrionalis) nesting in Chihuahua and Veracruz, Mexico, were analyzed for organochlorine pesticides, PCBs, and PBDEs. p,p'-DDE was the only organochlorine found in all eggs at concentrations ranging from 0.13 to 7.85 μg/g wet weight. PCBs ranged from 0.04 to 2.80 μg/g wet weight and PBDEs from 62 to 7...
The Veracruz Reef System (VRS), situated close to an important commercial port and receiving river discharges containing diverse pollutants from important agricultural and urban areas, is one of the marine regions in México where important impacts are observed from human activities. The VRS is ornithologically very important because the four North...
