Three whinny calls that are very different from each other. The first call has notes that all have the same high frequency level. The middle call is very short with some of the notes seeminly running together while the last call is the longest with the notes in the second half of the call having a lower top frequency compared to the notes in the first half. The audio was made while the Merlin was flying around a big grassy area attacking squirrels and some birds in a nearby yard.
