Calling where it counts: Subordinate pied babblers target the audience of their vocal advertisements
TL;DR: It is demonstrated that subordinate pied babblers adopt an alternative strategy for mate attraction by vocal advertisement from within their natal territories, and that subordinates focus their calling efforts on the edges of their territory, and specifically near boundaries with neighbouring groups that have potential breeding partners.
Is information from both quality signaling and social recognition really redundant? A comment on Sheehan and Bergman
TL;DR: Sheehan and Bergman (2016) have put together a thought-provoking and timely article on the importance of different types of assessment strategies in animals and argue that there is an evolutionary trade-off between the two, in that those that have developed quality signaling have little need for social recognition.

TL;DR: It is found kidnapping was a highly predictable event in pied babblers: primarily groups that fail to raise their own young kidnap the young of others, and it is shown this to be the theoretical expectation in a model that predicts kidnapping to be facultative.
