Record of albinism in European ground squirrel (Spermophilus citellus) (Rodentia: Sciuridae) in Slovakia

The European ground squirrel is a mammalian species whose populations are declining and has therefore become the target of various conservation projects in recent years. Currently, there are only a few dozen isolated populations in the Central European region. Increased interest in these animals has contributed to the first record of albino specimens of this species. A total of four juvenile individuals from two litters from one colony were observed, and in addition to the documentation itself, elementary behaviour notes were also made. All specimens did not survive to adulthood, confirming the low survival rate of aberrant individuals in the wild.
