Dolby and Grubb (2000) found that when core species (tufted titmice and Carolina chickadees) were present at a bird feeder far from forest cover, the latency for a satellite species (nuthatches) to begin feeding was much shorter than when the core species was absent. However, when the bird feeder was close to forest cover, feeding latency nuthatches did not differ according to whether cores species were present or absent. These results illustrate:
