  • We tested whether the temporal parameters of corncrake (Crex crex) call change seasonally and/or individually. We defined a new, compound variable called RHYTHM, which quantitatively describes how corncrake call is perceived. Temporal parameters of calls, including RHYTHM, were significantly associated with both the time within the breeding season and body size. The most striking variation of call production was related to between-call intervals, which define a range of calls from monotonous… CONTINUE READING
