Diving times and feeding rate by pecking in the Eurasian coot (Fulica atra)

We acquired data on diving times and feeding rates by pecking on three different substrates in a small wetland of central Italy, in order to improve the scant knowledge on foraging behaviour of the Eurasian coot (Fulica atra) in the Mediterranean area. Diving times showed a mean value of 2.59 sec (± 1.81 SD; n = 186). A large proportion of diving times (about 72%) were between 1 and 3 sec, a range corresponding to intrinsic physio-ecological times allowing a coot to search for food items below the water surface. The feeding rate by pecking was significantly higher in muddy soils when compared with either shallow water or rush beds. The data may be explainable in terms of the easier detectability and availability of different food items in muddy soils, which may increase the feeding rate by pecking on this substrate. The lower feeding rate in rush beds, when compared to muddy soils, could also be explained in terms of the spatial arrangement of this terrestrial substrate and, consequently, the higher level of predatory risk.
