(ABC 6 News) -- If your go-to sign of spring is the appearance of those warm-weather, feathered friends, you might be missing something this year.

Once again, you can blame the weather: Our recent extreme winter may have had an affect on the birds' traveling patterns.

Bird migration typically begins mid-April to the end of May, but this year, the birds are arriving much later and in different areas. Migration can slow or stop if the birds get stuck behind weather fronts. At other times, we may not see them if the weather is ideal and winds are favorable, beause the birds will pass right over our area.

One bird enthusiast said migration is about the sun.

"Birds don't depend on the weather in particular, they depend on the sunlight, so they're photosensitive to how the early days begin," said Terry Dorsey.

Dorsey said the delayed migration may also be because those birds haven't had access to the insects because the snow has delayed their appearance as well.
