What Do We Hope to Learn?
Survey data will help to answer a variety of questions about the lives and travels of hummingbirds, including:
- What are the nesting ranges and habitats
for each species?
- What is the schedule for spring and fall migration
for each species?
- What are the most important migratory corridors?
- How do natural nectar sources,
garden flowers, and feeders affect hummingbird distribution?
- How do weather and land uses affect nesting
and
migration?
- How well do different species adapt to
urbanization?
- How have drought and fire suppression affected
hummingbird distribution?
- Are hummingbird ranges changing in response to
global warming?
- Are Anna’s Hummingbirds continuing to
expand their range?
- Are any species expanding their winter
ranges?
