Journal 4 Maelean 1964 out the matter with Holmes and Pitelka, and finally works out a problem that is specific enough to grasp, broad enough to be useful in more than one sense, wise enough to, if desired, at least begin direction toward a Doctoral program, and flexible enough to be dissected into component parts which can produce results alone. (What you want, fellow, isn't a problem. What you want is a tinker toy!) Problem: Niche differentiation in sympatric congeneric species of sandpipers. Hypothesis: the species of Caliparin sandpipers breeding locally may differ in: a) time budget (esp. pectoral v. others) b) resting habits c) feeding habitat d) feeding technique e) food taken. Methods: A. What's here - investigation of insect fauna, from point of view of potential bird prey. 1) Besleze funnel and/or hand picked 500 samples. 2) Vacuum for surface insects. 3) Life histories of major components of insect fauna. All this section put off into future.
