The first migrant shorebirds appear, including Pectoral Sandpipers on their annual round-trip between the pampas of South America and the tundra of Siberia. Many wintering hawks and falcons depart. Local nesting activities start to intensify. April is the high month for Spring migration. The numbers of both the landbirds and shorebirds migrants peak.
Many local breeders begin their second nesting attempts.
The lagoons now seem quite empty. More landbird fledglings appear, and more second nesting attempts begin. And so the annual cycle of bird activities at Hornsby comes full circle, a cycle which can fully be appreciated only by considering each month of the year. Over the course of that year many tens of thousands of birds will stop at Hornsby Bend-some to rest and refuel for the next leg of their migration, others to overwinter, still others to raise their young. That's why Hornsby's preservation is so important-not only to the birds, but also to the humans whose lives are enriched by the birds which come from three continents and thousands of miles to stop at our Hornsby airport.
