Phenology and climate change in Africa and the decline of

birds departing for migration in poorer condition, or arriving too early or too late with respect to environmen-tal conditions or the availability of resources at their destination. There is already evidence that climatic and phenologi-cal change in Europe is a factor in population declines in migratory birds (Both et al. 2006; Samplonius et al

Factors Affecting the Survival of Barnacle Geese on Migration

The population is one of three groups of barnacle geese in the North Atlantic, but there is little or no interchange between them (see below). The Svalbard stock is the smallest; numbers declined to a low of only 300 birds in 1948, but the population has since been protected from shooting and many of its haunts have become reserves. Numbers rose to

Human activity shapes the wintering ecology of a migratory bird

Migrant birds are in decline across the world, raising concerns that many may lack the flexibility to rapidly respond and adapt (Both et al., 2010; Rosenberg et al., 2019; Sanderson et al., 2006). Whether migratory species have the capacity to adjust to rapid change is a focal question of current research. Many migratory birds,

Conserving migratory land birds in the New World: Do we know

Major advances in our understanding of the ecology of migrant land birds have occurred in the past 20 years (Faaborg et al. 2010). Here we discuss how these advances may guide modern conservation practices for migratory birds and ask what questions need to be answered to improve such conservation guidelines.

There are a variety of other ecosystem services that birds provide, including dissemination of seeds, nutrient and energy cycling, and predation of insects during nonbreeding seasons (Green 1995, Lanner 1996).

Jun 27, 2011 Twenty-three of the migratory species that occur here have been designated with some type of state or federal status for being at-risk due to population decline and threats. In 2003, the City of Portland was selected by the U.S. Fish and Wildlife Service (USFWS) to become a pilot city for the Urban Conservation Treaty for Migratory Birds Program.

Habitat ecology of Nearctic Neotropical migratory landbirds

Nearctic Neotropical migratory birds (Alerstam 1990). While important knowledge about full annual cycle dy-namics has increased greatly, our understanding of the specific drivers of population decline, especially in trop-ical wintering habitats, remains relatively poor (Runge and Marra 2005, Sherry et al. 2015).

resource use continues to increase due to human population and eco-nomic growth (Xu et al., 2017a, 2017b; Yang et al., 2017). Global change impacts the behavioural ecology, breeding performance and movement patterns of migratory birds (Di Maggio et al., 2018; Haest et al., 2018).

Climate warming, ecological mismatch at arrival and

population decline, and this evidence was not confounded by concomitant ecological factors or by phy-logenetic effects. These findings provide general support to the largely untested hypotheses that migratory birds are becoming ecologically mismatched and that failure to respond to climate change can have severe negative impacts on their
