Impact of climate change on hummingbird habitats.

Shifts in Flowering Phenology: Climate change alters the timing of flowering in plants, disrupting the synchronization between hummingbird arrival and peak nectar availability.

Habitat Range Shifts: Warmer temperatures and changing precipitation patterns can lead to shifts in vegetation zones

Loss of Habitat: Climate change contributes to habitat loss through factors such as deforestation, wildfires, and urbanization. Fragmentation and degradation of habitats 

Impact on Migration Patterns: Changes in temperature and weather patterns can affect the timing and routes of migration for hummingbirds.

Decreased Nectar Quality: Elevated CO2 levels can lead to changes in nectar quality, affecting its nutritional value for hummingbirds.

Competition and Predation: Climate change can alter the distribution and abundance of other species that interact with hummingbirds, such as competitors for resources

Extreme Weather Events: More frequent and intense extreme weather events, such as storms and droughts, can directly impact hummingbird populations by causing mortality
