Avian’s Survival Procedure

On the day I shot the pictures I’m posting today, our weather temperature  was very low and the breeze made it feel even colder!.

Most birds under windy or cold conditions trigger a natural survival mode which is a change on their feather layers covering their bodies.

The change consists of ruffling their down feathers under the upper feather layers and that effect makes their bodies retain their the warmth of the body temperature and reflect the cold from the outside with the top layers of feathers.

This a very natural procedure used by avians for a way to protect their bodies from losing the normal body temperature.

In the case of humans our bare skin would not resist cold temperatures for long. We resort to a similar principle by wearing clothes and a down parka or being inside a down-lined sleeping bag. Same principle apply to wearing clothes in layers for better protection, keeping the body temperature from escaping and at the same time reflecting the cold from affecting the body.

Fleece or animal fur work on the same principle or fat blubber for other animals.

The reason I brought up this subject is mainly because some people believe that they have eaten too much and turned obese, when they have seen a rounded shaped bird.

    • Thanks Jen! The shots are taken at different times and the light conditions vary from each other. The more light the sharpest it’s going to get (lower ISO). 🙂
