Nesting mice and young, thermography

Référence de la vidéo 12081024
Nesting mice and young, day 8 of 23. Thermographic timelapse footage of mice (Mus musculus) in their nest. Breeding mice produce an average of 6-8 young, which are born blind. The eyes open around 13 days after birth, and the young are weaned at around 21 days. The newborn young do not yet have the ability to regulate their own temperature. Their parents prevent them cooling down and dying by building a nest of insulating material and ensuring they are in near-constant contact with them. Thermography records the temperature of surfaces by detecting long-wavelength infrared radiation. The colours show variations in temperature. The scale (right) runs from white (warmest), through yellow, orange, red and purple to blue-black (coldest). This clip is part of a sequence of 20 showing the nesting mice and their young over a period of 23 days.
