Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
Hummingbird Central is going on its 11th year tracking the northward hummingbird migration. Ken Freeman, a Hummingbird Central staff member, says the site relies on "citizen spotters" to report ...
