Diel migrations of the golden shiner (Notemigonus crysoleucas) from the littoral to limnetic zone of a small Michigan lake were documented through visual observations and gill netting. During the day golden shiners schooled in the littoral zone. Just after sunset schools broke up and the golden shiner migrated to the open water regions of the lake. Feeding by the golden shiner was largely coincident with the evening migration. The majority of the shiner population fed on Daphnia and most prey were obtained within 1 h of sunset. Feeding was minimal through the night with some feeding evident at dawn. Daphnia underwent a strong diel vertical migration, especially larger individuals, and showed a strong horizontal gradient of decreasing size and density from the limnetic into the littoral region. Size of Daphnia eaten by the shiner increased dramatically across the evening feeding period. This increase is due to the horizontal gradient in Daphnia and availability of larger Daphnia as they migrate to the surface. On only one date when prey densities were highest did the shiners actively select large Daphnia. The golden shiner faces a dynamic prey system both in time and space which influences prey "selection." We relate adaptations of planktivorous fishes that migrate to relative abundances of fishes in small lakes. Key words: coevolution, Daphnia, diel migration, fish, foraging behavior, golden shiner, Notemigonus, planktivore, predator–prey

Tyrant Flycatchers

In this paper we present data on the foraging maneuvers and substrates used to capture preys by 28 species of tyrant flycatchers (Tyrannidae) in Brazil. For six species: Arundinicola leucocephala Linnaeus, 1764, Fluvicola nengeta Linnaeus, 1766, Machetornis rixosa Vieillot, 1819, Myiozetetes similis Spix, 1825, Pitangus sulphuratus Linnaeus, 1766, and Tyrannus melancholicus Vieillot, 1819 -, we go further to investigate perch height, search time, sally distance, and sally angle. With a few exceptions, sally strike was the most frequent foraging maneuver. Living foliage and air were the most frequent substrates used to capture preys. Among the six species studied in detail we found three distinct groups of perch heights: F. nengeta and M. rixosa foraged on the ground, A. leucocephala with P. sulphuratus were medium-height foragers, and T. melancholicus and M. similis form the third group for which prey attacks usually start from perches from the ground up to 3 m. With the exception of P. sulphuratus, which had the longest search time, the other five species did not differ in this aspect of the foraging behavior. Three groups were also discernible in relation to sally distance: F. nengeta and M. rixosa usually attacked prey close (< 2 m) to them, A. leucocephala, P. sulphuratus and M. similis form a medium-distance (3-4 m) group, and T. melancholicus had the longest sally distances (up to 12 m). Birds differ in details of the sally angle that, together with other subtle differences in the foraging behavior, may render important differences in prey selection.
