Please note that gooseberry bushes are highly toxic to birds (and even humans) because they contain hydrogen cyanide. If a goose, or other bird, eats the green leaves he or she can die a horrible, painful death. It is difficult to locate information about the toxicity of gooseberries on the Internet and the plant is not listed as toxic to birds on any lists I've seen so far.
Please, spread the word.
Ribes uva-crispa (European gooseberry)
