Position of birds eating sunflower seed is the niche dimension we explored in this exercise. In what other ways do birds seem to partition niche space at a bird feeder or series of feeders? Solution - There are three other ways do birds partition the niche space at a bird feeder. 1. Some birds eat the seeds at the perch of the feeder 2. Some more birds pick up the seeds at the feeder and fly away. 3. Few more birds pick up the seeds fallen near the niche at the bottom of the feeder. In this way niche space (within, bottom and away the feeder) is partitioned at the bird feeder by the birds..
