. Recordings were made in nests of Eretmochelys imbricata and 107 samples of 10-min recordings revealed 575 sounds that were classified manually into 4 categories. Our results show that hawksbill turtles vocalize within the nest, especially during and after eclosion, which suggests vocalizations are important for communication among hatchlings to synchronize emergence from the nest.
The understanding of developmental and reproductive migrations of sea turtles is essential for effective protection and conservation efforts. Flipper tags remain a valuable method for detecting movements and migrations because they are cost-effective and conspicuous, allowing the detection of a tagged animal by any person worldwide. Here we report 13 flipper-tag recoveries for Brazilian hawksbill ( Eretmochelys imbricata ) turtles that augment the body ofinformation on the migratory nature of this species and provide new growth-rate data.
