Though he makes periodic scientific trips to the world’s largest tropical wetland, the Pantanal of Brazil, to research & photograph wildlife there, when on San Mateo County’s Coast, Paul’s eyes and mind are very much captured by these main families of waders:  the Plovers , Sandpipers , Avocet & Stilts , & the Oystercatchers .  Look for Paul to tell you which of these waders can actually be found nesting in this area, and get ready with your questions, as Mr. Donahue’s knowledge in this area is deep.
