A male Leptodactylus latrans was observed calling within a foam nest located at about 40 cm from the edge of the pond. The male was collected (voucher deposited at the Herpetological Collection of the Museo Nacional de Historia Natural, Montevideo, Uruguay, MNHN 9476). Ten minutes after the calling male was removed, we observed an amplectic L. latrans pair laying eggs in the same nest. In addition, a third male was at the edge of the foam nest and sporadically swam under the amplectic pair.
