ABC’s Bird-Smart Wind Energy Campaign: Protecting Birds from Poorly Sited Wind Energy Development

Human-Wildlife Interactions, 2017
This article summarizes American Bird Conservancy’s (ABC’s) strategies and goals for achieving Bird-Smart wind energy in the United States. We describe the current and projected impact of wind energy development on birds and bats in the United States. We

Causal mechanisms for negative impacts of energy development inform management triggers for sagebrush birds

Ecosphere, 2023
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

Common Loon Reproductive Success in Canada: the West is Best but Not for Long

Avian Conservation and Ecology, 2013
Reproductive success of Common Loons (Gavia immer) is a powerful indicator of aquatic ecosystem health, especially in relation to mercury and acid precipitation. We examined relationships between Common Loon reproductive success and longitude, year, lake

Warming Arctic summers unlikely to increase productivity of shorebirds through renesting

Scientific Reports, 2021
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.

Modeling climate‐driven range shifts in populations of two bird species limited by habitat independent of climate

Ecosphere, 2023
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 ...

Sustainable management of fall armyworm in smallholder farming: The role of a multi‐channel information campaign in Rwanda

Food and Energy Security, 2023
In recent years, fall armyworm (FAW), Spodoptera frugiperda, has emerged as one of the most serious invasive species in many countries across Africa, Asia and Oceania.

Matching times of leading and following suggest cooperation through direct reciprocity during V-formation flight in ibis [PDF]

, 2015
One conspicuous feature of several larger bird species is their annual migration in V-shaped or echelon formation. When birds are flying in these formations, energy savings can be achieved by using the aerodynamic up-wash produced by the preceding bird ...

Using digital recordings and sonogram analysis to obtain counts of yellow rails

Wildlife Society Bulletin, 2016
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

Multi-sensor geolocators unveil global and local movements in an Alpine-breeding long-distance migrant

Movement Ecology, 2023
Background To understand the ecology of long-distance migrant bird species, it is necessary to study their full annual cycle, including migratory routes and stopovers.
