Estimated population trends can identify declining species to focus biological conservation, but monitoring may fail to illuminate causes of population change and strategies for reversing declines. Monitoring programs can relate trends with environmental

Warming Arctic summers unlikely to increase productivity of shorebirds through renesting
Climate change in the Arctic is leading to earlier summers, creating a phenological mismatch between the hatching of insectivorous birds and the availability of their invertebrate prey.

Ranges of species around the world are expected to contract in response to climate change. Species distribution models (SDMs) are a powerful tool for predicting changes in habitat availability, but the variables selected to create SDMs influence their ...

Abstract Our knowledge of the recent Avifauna of the island of Rodriguez has hitherto been confined to a few memoirs published by Mr. Edward Newton, and Professor Alfred Newton of Cambridge. The former has given us an account of a hurried trip of a few days duration made by him in 1864 (Ibis, 1865, pp.

Using digital recordings and sonogram analysis to obtain counts of yellow rails
Autonomous recording units (ARUs) are emerging as a useful technology for the study and monitoring of animals that produce vocalizations. During summer and fall of 2013, we performed a series of experiments aimed at developing sampling protocols to count
