What weather is suitable for releasing pigeons in summer?

Generally speaking, pigeons on sunny days tend to have a smooth head, that is, the front is small and the back is large, the neck is generally not very long, and the luster of feathers will be better. Pigeons suitable for cloudy days have round heads.

Many fast pigeons on sunny days are relatively small, and of course there are some pure breeding pigeons. In fact, whether pigeons are suitable for flying in sunny days or cloudy days depends mainly on their eyes. For example, it is obvious that pigeons tend to have smaller pupils on sunny days and larger pupils on cloudy days. These are some characteristics of pigeons in different weather. Of course, when we want to see what weather pigeons are suitable for, we should mainly consider the issue of pedigree. For example, some purebred pigeons are large in size, but suitable for flying in sunny days, and some purebred pigeons are small in size and suitable for flying in sunny days.
