The saltmarsh sparrow exhibits several adaptations to flooding, including nest repair, egg retrieval, rapid re-nesting, and synchronization of breeding with the lunar cycle. [24] [25] Nesting begins immediately following a spring tide, allowing young to fledge before the next spring tide. [25] Two broods are typically raised per breeding season ...
In 1995, sharp-tailed sparrows were divided into two separate species: the Nelson's sharp-tailed sparrow (Ammodramus nelsoni) and the saltmarsh sharp-tailed sparrow (Ammodramus caudacutus). Saltmarsh sharp-tailed sparrows are found in salt marshes along the Atlantic coast from the Delmarva Peninsula north to southern Maine. Within the refuge ...
