""We are often using a scope. Which allows us to see birds that are far away," said Julian Wood, SF Bay Program Leader at Point Blue Conservation Science. "When I'm doing the tidal marsh surveys, I'm often using binoculars since I'm walking around in the mash. A lot of those surveys are done by ear I can hear birds calling and singing and identify what species they are.""
""I was shocked. The declines range from 25% to 86% for some of these birds since 2006," said Wood. For almost a year, scientists monitored about 20 different bird species, five in different habitat groups and had over 100 volunteers involved. The last time they published a report like this one was in 2011. This new review is trying to "raise awareness about what the needs are for some of those species and how to reverse those declines," said Wood."
Scientists monitoring birds across the San Francisco Bay use scopes, binoculars and auditory surveys to track populations in tidal marshes and other habitats. Monitoring of about 20 species across five habitat groups involved more than 100 volunteers and one year of surveys. Shorebird populations have declined markedly over the past two decades, with some species showing declines between 25% and 86% since 2006. Declines likely reflect lower reproductive success and higher mortality among different species. Some species show stable or improving signs, and targeted conservation actions aim to raise awareness and reverse declines.
