Stopover strategies in birds: a review of methods for estimating stopover length [PDF]
Bird Study, 1999 This study categorizes and reviews methods used to estimate stopover length in migratory birds. Stopover length is an important variable in analysing migration strategies. The analysis of the stopover pattern of migratory birds typically attempts to investigate variability in the number of stopovers and in the length of time spent at stopover sites in ...

Feather growth rate and mass in nearctic passerines with variablemigratory behavior and molt pattern [PDF]
, 2012 Bird species vary greatly in the duration of their annual complete feather molt. However, such variation is not well documented in birds from many biogeographic areas, which restricts our understanding of the diversification of molt strategies.

Stopover duration of spring migrating dabbling ducks in the Wabash river valley
Wildlife Society Bulletin, 2019 Waterfowl use stopover sites during spring migration to rest and replenish nutrient reserves prior to their arrival on breeding grounds. Estimating the extent to which an individual remains at a stopover site before dispersing (i.e., stopover duration ...

Frontiers in Ecology and Evolution, 2018 Avian influenza has advanced from a regional concern to a global health issue with significant economic, trade, and public health implications. Wild birds, particularly waterfowl (Anseriformes), are known reservoirs for low-pathogenic avian influenza ...

Remote Sensing, 2020 The distributions of birds during migratory stopovers are influenced by a hierarchy of factors. For example, in temperate regions, migrants are concentrated near areas of bright artificial light at night (ALAN) and also the coastlines of large water ...

Charging electric vehicles using opportunistic stopovers [PDF]
2017 IEEE International Conference on Environment and Electrical Engineering and 2017 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2017 The diffusion of electric vehicles asks for efficient energy replenishment, which requires geographical and temporal coordination of shared charging resources. We introduce a novel charging methodology that exploits users' opportunistic mobility. This paper focuses on vehicle stopovers detecting potential charging opportunities.

Toward Self-Organising Service Communities [PDF]
, 2005 This paper discusses a framework in which catalog service communities are built, linked for interaction, and constantly monitored and adapted over time. A catalog service community (represented as a peer node in a peer-to-peer network) in our system can ...

Journal of Avian Biology, 2022 Migration patterns in birds vary in space and time. Spatial patterns include chain, leapfrog and telescopic migration. Temporal patterns such as migration duration, number, and duration of stopovers may vary according to breeding latitude, sex, and ...

Migrating birds rapidly increase constitutive immune function during stopover
Royal Society Open Science, 2020 Migratory flight is physiologically highly demanding and has been shown to negatively affect multiple parameters of constitutive immune function (CIF), an animal's first line of physiological defence against infections. In between migratory flights, most
