The Winter Hummingbird at Our Community – Science 26

Generally, hummingbirds have visited our state by late February to early March and gone by late Summer.

In case of winter hummingbirds, sure, they will arrive and stay in our areas during winter seasons. Southern states winter is a little bit friendly than frozen winter in northern states.

There are many species of winter hummingbirds, but three the most seen in our neighborhoods:

- Rufous hummingbird
- Calliope hummingbird
- and Allen's hummingbird

What make us wonder that why does Rufous hummingbird show up early in our neighborhood?

What are factors trigger them to do migration early?

First, I read it is due to daylight changes. I don’t know whether this reason is true or false. Quite strange for me.

Second, shortage of food resources such as insects, nectar and flower in areas where winter hummingbirds come from.

Finally, severe temperature in northern part of America. Frozen temperature may trigger winter hummingbirds to arrive early in our areas.
