Our visitor author, Carleton Eyster, an Avian Ecologist with Level Blue Conservation Science and Avocet Analysis Affiliation (ARA), has been on the entrance strains of defending Western Snowy Plovers within the San Francisco Bay Space for years. In Half I, Carleton shared how susceptible Snowy Plover eggs got here into care at Hen Rescue. Right here, he explores inventive options to guard these birds and preserve them from needing rescue within the first place.
Defending Threatened Species in a Distinctive Habitat
This 12 months, biologists with ARA monitored Snowy Plovers at Montezuma and Novato Baylands and carried out measures to spice up chick survival within the North Bay. Novato Baylands and Level Reyes Nationwide Seashore stay a testing floor for nest safety methods highlighted in Half I.
Ongoing monitoring will information how North Bay wetlands assist breeding shorebirds, together with Snowy Plovers, as restoration evolves. Over the previous three years, roughly a dozen breeding Snowy Plovers at Novato Baylands have efficiently raised over two dozen juveniles. The location now helps 20 or extra plovers, a significant achieve for a species with fewer than 2,000 people left in California.
Though Novato and Montezuma are at the moment the one often occupied breeding websites within the North Bay, biologists are discovering Snowy Plovers utilizing a wide range of micro-habitats throughout marshes and bayshore. These wetlands are dynamic, shifting with tides, rainfall, and restoration progress. Snowy Plovers favor early stage wetlands and are nicely tailored to relocate as circumstances change, just like their habits in seashore and dune environments.
Nesting Challenges and Artistic Options
At Montezuma Wetlands, biologists discovered Snowy Plovers nesting on newly deposited dredge fill meant to create brackish marsh habitat. The early levels of restoration create naked salt panne habitat that pulls nesting plovers. Nevertheless, sadly, the sediment layers can kind extensive cracks too deep for susceptible chicks to cross.
To stop chick mortality in cracked sediment, biologists collected eggs and transferred them to Hen Rescue for protected hatching and care. As the subsequent part of the Montezuma mission approached and the pond was set to flood, the staff chosen Novato Baylands as the discharge web site.
17 fledglings had been launched at Novato Baylands, every color-banded for future identification and monitoring. A number of teams, together with ARA, San Francisco Bay Hen Observatory and Level Blue Conservation Science, are monitoring plover actions. Their observations reveal vital connections between wetlands and coastal websites throughout the higher Bay Space.
The hope is these younger plovers will settle in and breed on the Seashore and Novato Baylands the next 12 months. The longtime collaboration between NPS, PRNSA, and Level Blue helps threatened Western Snowy Plover populations stay regular all through the higher Bay Space, and up and down the coast because the birds transfer.
Conclusion: Companions in Wildlife Duty
In a quickly altering world, Hen Rescue is dedicated to wildlife accountability by way of rehabilitation, conservation, and collaboration. We’re proud to companion with mission-aligned organizations like our visitor writer Carleton, ARA, NPS, PRNSA, and Level Blue to guard susceptible species just like the Western Snowy Plover.
Whereas our rehabilitation facilities present year-round care alongside the Pacific Flyway, our impression doesn’t finish there. By way of multi-lateral partnerships, we cut back danger and enhance outcomes for wildlife on a bigger scale. From consulting with the Port of Los Angeles Wildlife Affect Mitigation Mission to advising CalTrans on cormorant condos in the course of the previous Bay Bridge removing, and creating the Elegant Tern Job Pressure, our staff works with public businesses, companies, and biologists to forestall hurt, shield younger birds, and assist long-term conservation options.
