abstract = "Alarm signals have evolved to communicate pertinent threats to conspecifics,
but heterospecifics may also use alarm calls to obtain social information. In
birds, mixed-species flocks are often structured around focal sentinel species,
which produce reliable alarm calls that inform eavesdropping heterospecifics
about predation risk. Prior research has shown that Neotropical species
innately recognize the alarm calls of a Nearctic sentinel species, but it remains
unclear how generalizable or consistent such innate signal recognition of
alarm-calling species is. We tested for the responses to the alarm calls
of a Neotropical sentinel forest bird species, the dusky-throated antshrike
(Thamnomanes ardesiacus), by naive resident temperate forest birds across
three continents during the winter season. At all three sites, we found that
approaches to the Neotropical antshrike alarm calls were similarly frequent
to the alarm calls of a local parid sentinel species (positive control), while
approaches to the antshrike’s songs and to non-threatening columbid calls
(negative controls) occurred significantly less often. Although we only
tested one sentinel species, our findings indicate that temperate forest birds
can recognize and adaptively respond globally to a foreign and unfamiliar tropical
alarm call, and suggest that some avian alarm calls transcend
phylogenetic histories and individual ecological experiences.",
