eBird breeding and non-breeding season dates are defined for each species as the weeks when the species\u2019 population does not move. For this reason, these seasons are also described as stationary periods. The dates were defined by experts in the status and distribution of birds based on the weekly abundance maps. The selected dates were then checked to make sure that they generally matched expected patterns of phenology for the species. Refer to <\/SPAN>eBird Status and Trends<\/SPAN><\/SPAN><\/A> for more information.<\/SPAN><\/P>

eBird data were downloaded by CNHP 20250804 under a Data Licensing Agreement for the 2025 SWAP.<\/SPAN><\/P>
