The Claim

Pacific green tree frogs produce mating calls to attract mates.

Verified by Lenz ·

The Short Version

The core biological claim is supported. Reliable studies and institutional references show that male Pacific treefrogs/Pacific chorus frogs produce advertisement calls during the breeding season that attract females. The caveat is that "Pacific green tree frog" is a nonstandard name in the evidence, and the calling behavior is specifically a male mating behavior.

Caveats

  • The evidence is for Pacific treefrog/Pacific chorus frog (Pseudacris regilla); "Pacific green tree frog" is not the standard name used in the cited sources.
  • The mating or advertisement call is primarily produced by males to attract females, so the claim is overbroad if read as applying equally to all frogs in the species.
  • These calls can also serve other functions, such as territorial or male-male signaling, so reducing them only to mate attraction oversimplifies their role.
