A 10-year study in Scotland showed that Eurasian sparrowhawks did not select the common redshanks they predated according to the waders' size or condition, probably because of the hawks' surprise-attack hunting technique. [52] In Britain, the increase in population of the Eurasian sparrowhawk coincides with the decline of the house sparrow ...
