TLDR
Puerto Rico has nearly as many bird species per layer as Panama and the temperate regions, but the Puerto Rican species appear to recognize fewer layers and certainly subdivide habitats much less, so different habitats are likely to have quite similar species in Puerto Rico, unlike Panama and temperate United States.Abstract:
Breeding bird censuses were made in Puerto Rico, Panama, and temperate United States, and a profile of foliage density was made for each. Using information theory formulae both diversity indices and measurements of difference between censuses and difference between habitats can be made. Based on these, the following can be verified directly from the data: 1. Puerto Rico has nearly as many bird species per layer as Panama and the temperate regions, but the Puerto Rican species appear to recognize fewer layers and certainly subdivide habitats much less. Thus different habitats are likely to have quite similar species in Puerto Rico, unlike Panama and temperate United States.read more

Ecological Diversity and its Measurement
TL;DR: In this paper, the authors define definitions of diversity and apply them to the problem of measuring species diversity, choosing an index and interpreting diversity measures, and applying them to structural and structural diversity.

Diversity and Evenness: A Unifying Notation and Its Consequences
TL;DR: Three commonly used measures of diversity, Simpson's index, Shannon's entropy, and the total number of species, are related to Renyi's definition of a generalized entropy, according to which there is a continuum of possible diversity measures.

A General Hypothesis of Species Diversity
TL;DR: A new hypothesis, based on differences in the rates at which populations of competing species approach competitive equilibrium (reduction or exclusion of some species), is proposed to explain patterns of species diversity.

Birds of the West Indies
TL;DR: From Grand Bahama Island in the north to Grenada in the south, this guide covers a tropical avifaunal region which includes such species as the tiny bee hummingbird, parrots, honey-creepers and todies as discussed by the authors.
