Geographic patterns in relative abundances and population trends of breeding and wintering loggerhead shrikes in North America Geographic patterns in relative abundances and population trends of breeding and wintering loggerhead shrikes in North America
In North America, the Breeding Bird Survey and the Christmas Bird Count provide data that are collected at sites visited each year, and the site-specific data can be placed in a Geographic Information System and smoothed to produce contour maps of relative abundance and trend for the United States and southern Canada. We develop these contour maps for Loggerhead Shrike (Lanius...

Estimating bird species richness from capture and count data Estimating bird species richness from capture and count data
We used capture-recapture methods to estimate bird species richness from mist-net and point-count data from a study area in Campeche, Mexico. We estimated species richness separately for each survey technique for two habitats, forest and pasture, in six sampling periods. We then estimated richness based on species' detections by either technique, and estimated the proportion of species...

Population trends from the North American Breeding Bird Survey Population trends from the North American Breeding Bird Survey
INTRODUCTION: Most Neotropical migrant birds are difficult to count accurately and are moderately common over large breeding distributions. Consequently, little historical information exists on their large-scale population changes, and most of this information is anecdotal. Surveys begun in this century such as Breeding Bird Censuses and Christmas Bird Counts have the potential to...

Comments on the status of revived old names for some North American birds Comments on the status of revived old names for some North American birds
We discuss 44 instances of the use of generic, specific, or subspecific names that differ from those generally in use for North American (sensu AOU 1957) birds. These names are generally older than the names presently used and have been revived on the basis of priority. We examine the basis for the proposed changes and make recommendations as to which names should properly be used in an...

Ecological and toxicological aspects of the partial meltdown of the Chernobyl nuclear power plant reactor Ecological and toxicological aspects of the partial meltdown of the Chernobyl nuclear power plant reactor
the partial meltdown of the 1000-MW reactor at Chernobyl, Ukraine, on April 26, 1986, released large amounts of radiocesium and other radionuclides into the environment, causing widespread radioactive contamination of Europe and the former Soviet Union.1-7 At least 3,000,000 trillion becquerels (TBq) were released from the fuel during the accident (Table 24.1), dwarfing, by orders of...

The Altay falcon: Origin, morphology and distribution The Altay falcon: Origin, morphology and distribution
The systematic position of the Altay falcon (Falco altaicus lorenzi) is perhaps the most enigmatic question lingering in falcon taxonomy. First reported to science in 1811, it has been treated as a race of the gyrfalcon (F. rusticolus), as a race of the saker (F. cherrug), as two separate species (F. lorenzi and F. altaicus), and as one to three color morphs of either the saker or the...
