Modeling Regional Source-Sink Dynamic

For Migratory Songbirds in Inform Management Practices on Department of Defense Installations

Maintaining viable populations of migratory songbird species remains a priority management issue for the Department of Defense. Habitat quality often influences population viability; high-quality habitats have more births than deaths (sources) and low-quality habitats have more deaths than births (sinks).

As such, managing migratory bird populations on more than 30 million acres of critical wildlife habitat requires detailed knowledge of patterns of birth and death through time and how land use practices and landscape configuration influence vital rates and population persistence.

In addition, many migratory songbird species spend the majority of their annual cycle in tropical latitudes, which requires managers to understand how the overwinter period influences population dynamics.
