Diet and Foraging

Very little information.

There are few published data on the feeding and foraging behaviors of the White-throated Antpitta. It is said to forage largely on, or near, the ground (9 Krabbe, N., and T. S. Schulenberg (2003). Family Formicariidae (ground-antbirds). In Handbook of the Birds of the World. Volume 8: Broadbills to Tapaculos (J. del Hoyo, A. Elliott, and D. A. Christie, Editors). Lynx Edicions, Barcelona, Spain. pp. 682–731. Close , 2 Schulenberg, T. S., and G. M. Kirwan (2012). White-throated Antpitta (Grallaria albigula). In Neotropical Birds Online (T. S. Schulenberg, Editor), Cornell Lab of Ornithology, Ithaca, NY. Available at https://doi.org/10.2173/nb.whtant2.01. Close ), and presumably hunts by probing into the leaf litter and soil with its heavy bill, occasionally gleaning prey from low vegetation.

Insectivorous, but the diet is not described in any detail. Stomach contents (n = 2) included caterpillars (4.5 cm long, one each in both stomachs), spiders, roaches, and other unidentified insects (9 Krabbe, N., and T. S. Schulenberg (2003). Family Formicariidae (ground-antbirds). In Handbook of the Birds of the World. Volume 8: Broadbills to Tapaculos (J. del Hoyo, A. Elliott, and D. A. Christie, Editors). Lynx Edicions, Barcelona, Spain. pp. 682–731. Close , 2 Schulenberg, T. S., and G. M. Kirwan (2012). White-throated Antpitta (Grallaria albigula). In Neotropical Birds Online (T. S. Schulenberg, Editor), Cornell Lab of Ornithology, Ithaca, NY. Available at https://doi.org/10.2173/nb.whtant2.01. Close ). Although earthworms are not known in their diet, the apparent prevalence of earthworms in the diets of other Grallaria (4 Greeney, H. F. (2018). Antpittas and Gnateaters. Christopher Helm, London, UK. Close ), combined with the species’ largely terrestrial habits, suggests that earthworms are likely also a part of their diet.
