In the Special Feature, Ecology and Conservation of Cavity Nesters in the Neotropics, seven field studies, a perspective, and a review contribute to understanding the ecology and conservation of cavity-nesting birds through a Neotropical lens.
“I joined AOS to connect with a diverse community of scientists dedicated to bird conservation. AOS provides opportunities to engage with like-minded researchers, stay informed about advances in ornithology, and share my passion for waterbird research.”
For more than a decade, our team has focused on studying male Scolopax minor (American Woodcock) in Rhode Island. During this time, we recognized a significant gap in knowledge about female S. minor, particularly regarding nest site selection and brood survival, due to a lack of data from this region.
