For the last 5 years Leslie Canyon NWR has run a MAPS (Migratory Avian Production Survey) station to monitor avian species that utilize the refuge.  Nine banding sessions were completed in 2007 following MAPS protocol, with a grand total of 540 net-hours (where one net-hour is the equivalent of one 12-m net open for one hour). 

The 2007 season resulted in 339 bird captures of 45 species (0.6 birds per net-hour); 65 of the captures were re-captures from previous efforts.  This compares to 2006 season data which resulted in 433 bird captures of 48 species (0.8 birds per net hour) and 50 recaptures. It is believed that the reason for the decline in captures from last year is due to more availability of water in the region. 

The ten most-commonly-captured species during 2007 were: Black-chinned Hummingbird (12%); House Finch (12%); Blue Grosbeak (10%); Lucy’s Warbler (10%); Broad-billed Hummingbird (6%); Varied Bunting (5%); Nashville Warbler (5%); Yellow Warbler (4%); Summer Tanager (4%); and Western Tanager (3%).
