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

open access: yesEcosphere, 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

Warming Arctic summers unlikely to increase productivity of shorebirds through renesting

open access: yesScientific 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

open access: yesEcosphere, 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 ...

Birds [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London, 1879
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.

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

open access: yesFood 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.

Minimum capture-recapture rates and years of banding station operations to obtain reliable adult annual survival estimates

open access: yesJournal of Field Ornithology, 2022
We examined variability in adult annual survival rate estimates for 33 breeding bird species, using 2011–2019 data from a 38-station Monitoring Avian Productivity and Survivorship (MAPS) program in Alberta, Canada.

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

open access: yesWildlife 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

open access: yesMovement 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.

Miniaturized multi-sensor loggers provide new insight into year-round flight behaviour of small trans-Sahara avian migrants

open access: yesMovement Ecology, 2018
Background Over the past decade, the miniaturisation of animal borne tags such as geolocators and GPS-transmitters has revolutionized our knowledge of the whereabouts of migratory species.
