Ever since Horace Wright wrote about the birds of Pondicherry in his book The Birds of the Jefferson Region in the White Mountains (1911), the refuge has been a popular area for birding and offers one the chance to see an impressive variety of birds. The checklist for the refuge includes a total of 241 species that have been seen since 1899 when Wright began his record-keeping. Of this number, 122 are species that breed in the refuge. Designated the first Important Bird Area in New Hampshire in 2004, Pondicherry is also a stop on the Connecticut River Birding Trail, which highlights birding sites in the Connecticut River watershed.
Although birds are seen year-round at Pondicherry, the prime time for birding is between April and November, with May and June being the best months for warblers and September and October the best months for migrating waterfowl. Favorite locations for birding in the refuge include Cherry Pond, Little Cherry Pond, Moorhen Marsh, and Mud Pond, all easily accessible by the hiking trails at the refuge. Although not part of the refuge, Airport Marsh (located on Airport Road about a mile northwest of the Pondicherry Rail Trail parking lot) is also a good spot to bird.
