For approximately how long are nestlings of the Eurasian Wryneck provisioned almost exclusively with ants inside the nest cavity?
Answer
Roughly twenty days
The dietary needs of the developing young mirror the adults, emphasizing the fundamental role of ants for reproductive success. For the Eurasian Wryneck, both parents participate in feeding the chicks inside the nest cavity. The nestlings receive provisions composed almost exclusively of ants and ant larvae for a specific duration, which is stated to be roughly twenty days until they reach the stage where they are ready to fledge. Following this initial period in the cavity, parental commitment continues for an additional seven to ten days post-fledging, during which they supply food and actively teach hunting skills.
