The difference between houses and trees (sparrows)
To expand my familys’ and friends’ basic knowledge of birds – a short summary of the main differences between tree sparrows (skovspurv) and house sparrow (gråspurv) – good luck!
Tree sparrow / skovspurv: Male and female are similar, and a tip to remember: both have been playing the the forest (think trees) and have “dirty cheeks”!
House Sparrow / Gråspurv: The male and female are different, but they have been playing indoors (in the house) and therefore have “clean cheeks”. (Det virker ikke så godt på Dansk!)
