The objectives of this study were to 1) determine whether avian and mammalian predator activity, density, and space use can be successfully detected and quantified using camera traps, 2) employ multiple field techniques to estimate the activity, density, and space use of the array of species that

From 2008 to 2014, SFBBO conducted a pilot study investigating the effects of oyster shell habitat enhancement on Snowy Plover nesting success. One hectare test plots were distributed on salt pond bottoms in Eden Landing Ecological Reserve (Eden Landing), Hayward, California.
In 2011, we recorded Snowy Plover numbers, site use, nest success, fledging success, use of habitat enhancement project sites, species of nest predators and avian predator numbers throughout the Snowy Plover breeding season.
In 2010, we recorded Snowy Plover numbers, site use, nest success, fledging success, use of habitat enhancement project sites, species of nest predators and avian predator numbers throughout the Snowy Plover breeding season.
Our objectives are to determine the impact of gulls on breeding snowy plovers and Forster’s terns.; Color-mark California gulls at A6 to determine potential nesting distributions after restoration of A6.; Continue our California gull colony surveys to document current population size.
This study addresses these questions: What is the flush rate and flush distance of nesting snowy plovers in response to new trail use around seasonally-dry ponds where birds nest? Do plovers respond differently to people who have disturbed them versus people they have not seen before?
