Résumé

Recent observations of the Gray Treefrog, Hyla versicolor, in the Maritimes suggest that this species may be expanding its range and abundance, perhaps partly in response to human activities. However, during the breeding season the species characteristically calls in very small choruses in the region and may be present but not call, or call for very short periods. This has made it difficult to determine distribution and to make an assessment of unconfirmed historic records that suggest presence beyond the current range more than 50 years ago. The inadvertent introduction of frogs may also be playing a role in the apparent recent range expansion of this species.
