What are the challenges hummingbirds face?

Hummingbirds face several challenges, including habitat loss due to deforestation and urban development, which reduces their access to nectar-rich flowers. Climate change also affects their migratory patterns and food availability, disrupting their breeding and feeding cycles. Additionally, competition for resources from other birds and the impact of pesticides can further threaten their populations. Conservation efforts are essential to mitigate these challenges and protect their habitats.
