often 1 day. Usually combined with focal-animal sampling, this is an excellent but difficult method for recording foraging and feeding behavior. Start-and-stop rules, independent of the behavior being studied, are required.
Sequence Sampling. A sampling period starts with the beginning of a sequence of a chain of behaviors, such as foraging for insects and feeding. The sampling period ends when the observed sequence ends. This method is of lim-
