What does the presence of the Western Tanager signal regarding habitat health?
Answer
A healthy mix supporting foliage for gleaning and open air for hawking insects
The Western Tanager functions as an ecological indicator because its survival depends on a specific seasonal resource structure. Its presence signals a habitat that successfully supports both the summer needs and the autumn migration needs. Specifically, it requires a healthy mix that provides dense foliage necessary for gleaning static prey, combined with sufficient open air space for active hawking of flying insects during the summer breeding months, alongside the necessary native berry-producing shrubs to fuel the southbound flight.
