FunGramKB is a lexico-conceptual knowledge base for NLP systems. The FunGramKB lexical model is basically derived from OLIF and enhanced with EAGLES/ISLE recommendations with the purpose of designing robust computational lexica. However, the FunGramKB interlingual approach gives a more cognitive view to EAGLES/ISLE proposals. The aim of this paper is to describe how this approach influences the...

--A field experiment, offering a choice of two prey fish of unequal sizes to foraging Bald Eagles (Haliaeetus leucocephalus), was devised. The objective of the field experiment was to determine if eagles preferred one prey item over another, and if this preference varied between breeding and non-breeding seasons. A total of 67 trials were conducted on four nesting pairs of eagles, 32 trials in ...

ISLE (International Standards for Language Engineering), a transatlantic standards oriented initiative under the Human Language Technology (HLT) programme, is a continuation of the long standing EAGLES (Expert Advisory Group for Language Engineering Standards) initiative, and is carried out by European and American groups within the EU-US International Research Co-operation, supported by EC and...

We report three new avian mitochondrial genomes, two from widely separated groups of owls and a falcon relative (the Secretarybird). We then report additional progress in resolving Neoavian relationships in that the two groups of owls do come together (it is not just long-branch attraction), and the Secretarybird is the deepest divergence on the Accipitridae lineage. This is now agreed between ...

To maximize fitness, flying animals should maximize flight speed while minimizing energetic expenditure. Soaring speeds of large-bodied birds are determined by flight routes and tradeoffs between minimizing time and energetic costs. Large raptors migrating in eastern North America predominantly glide between thermals that provide lift or soar along slopes or ridgelines using orographic lift (sl...

In this study, we report hematocrit and plasma chemistry values for adult captive collared scops owls (Otus lettia) and crested serpent eagles (Spilornis cheela hoya). In particular, we address the gender-specific differences within these values. We measured hematocrit (HCT) and plasma chemistry values for uric acid (UA), plasma urea nitrogen (BUN), total protein (TP), albumin (ALB), glucose (G...

Problems with golden eagle (Aquila chrysaetos) and bald eagle (Haliaetus leucocephalus) depredation on livestock in western United States were investigated by surveying Animal Damage Control field personnel. One hundred forty-three individuals from 14 states identified areas where they had observed eagle damage to livestock in the past 10 years. Most field personnel believed golden eagles (both...

Bald eagles (Haliaeetus leucocephalus) may be at risk from contaminants in their diet and young birds may be particularly sensitive to contaminant exposure. To evaluate potential risks from dietary mercury exposure to eagle nestlings in South Carolina (USA), we surveyed mercury concentrations in 34 nestlings over two breeding seasons (1998 and 1999). Samples were also obtained from several post...
