I was out for a walk this afternoon on the moors above Holmfirth and I spotted this white Mountain Hare trying to hide in the heather. I edged closer until I was almost nose to nose with him. But he remained totally motionless, thinking I cannot have spotted him with his marvellous camouflage.

The Mountain Hares in the Peak District were introduced from Scotland during the Nineteenth Century. But in Scotland the snow cover is more prolonged and predictable so the white pelage keeps them camouflaged in winter. But snow is not nearly as frequent or persistent in the Peak District, but the Hares still turn white in winter, where they stand out like sore thumbs. One of their key predators in Scotland is Golden Eagle, which will maintain the colour change through Natural Selection (a hare that doesn't turn white in Scotland during winter will be more likely to be spotted by an eagle). But there are no eagles in the Peak District so this population lacks the main selective force for maintaining adaptive colouration.

The collared owlet, being Asia's smallest owl species, measures between 15 and 17 cm. Females are generally larger than the males, weighing approximately 63 grams, whereas males weigh in at 52 grams.

This bird has a grey-brown colour (depending on age-morph) and has a barred back and flanks, while the head is more spotted than barred.[6] They have prominent white eyebrows, vibrant lemon-yellow-coloured eyes and a white throat patch. The chin, center of the breast and belly are mostly white.The pale collar and the two black spots on each side of the nape imitate eye spots and make it seem like the owl is staring at you from behind. This is known as the "occipital face". It has a greyish-brown pale-spotted pectoral band on upper breast and lacks ear-tufts. You can see its tail when in flight, longer than most pygmy owls, and has rapid wingbeats.
