Priorities for migratory networks

More than any other Australian pigeon, the nomadic flock bronzewing
is adapted to the arid plains. The preferred habitat is open grassland
plains, clumped grasses and small shrubs with open spaces. The main
impact on flock bronzewings has been through pastoralism as stock feed
on the grasses the bird uses for food and nesting. In the mid 1800s, many
observers wrote about the enormous flocks of the flock pigeons within
areas where they are now just occasional visitors such as northern South
Australia and western New South Wales. (Photo by Jeremy Ringma )

Looking after our nomads

Geographic range size and extinction risk Geographic range size (the size of a species’ distribution) is often treated as a fixed attribute of a species for the purposes of calculating extinction risk (see the segment below, on EOO & AOO). All else being equal, species occupying smaller geographic ranges are assumed to have a higher risk […]

The vital bits of a monarch’s migration

Conserving migratory animals has always been a challenge because they face a range of threats at different parts of their migration, often separated by vast geographical distances (consider the threat to migratory birds from the loss of tidal flats in Asia, see p8). Addressing threats to population viability of migratory animals therefore requires integrating information of how individuals move, survive and reproduce throughout their annual cycle
