In winter life can be hard for animals – days are short and for many creatures finding enough food to survive takes up almost every hour of daylight. But there is still plenty of wildlife to spot.

There is fantastic wildlife to see during spring. Birdsong reaches a peak and many flowers appear, in turn attracting insect-life, including bees and butterflies. Animals that hibernated over winter begin to appear.

Yn y gaeaf gall bywyd fod yn anodd i anifeiliaid - mae dyddiau'n fyr ac i lawer o greaduriaid mae dod o hyd i ddigon o fwyd i oroesi yn cymryd bron bob awr o olau dydd. Ond mae yna ddigon o fywyd gwyllt i'w weld o hyd.

Mae bywyd gwyllt gwych i'w weld yn ystod y gwanwyn. Mae cân adar yn cyrraedd uchafbwynt ac mae llawer o flodau yn ymddangos, yn eu tro yn denu bywyd pryfed, gan gynnwys gwenyn a gloÿnnod byw. Mae anifeiliaid sy'n gaeafgysgu dros y gaeaf yn dechrau ymddangos.
