The trypanosome from kestrel represents an exception in this respect, since only isolates from adult birds were available.
The following trypanosomes of raptors were successfully isolated into culture and cryopreserved : 31 isolates from buzzards, 21 isolates from sparrowhawks, 2 isolates from kestrels, and 7 isolates from lesser-spotted eagles.
The kestrel undoubtedly is in no danger of extinction at the present time.
The species were lanner falcon, kestrel, various birds of the parrot family, skins of tiger, leopard, serval and genet, and cactus plants.
People cannot destroy kestrels, stoats, and so on, and then not expect the water rat to grow in number.
The greatest amount of damage that is done by hawks is done by the sparrowhawks, and damage is also done by the kestrel occasionally.
I have seen kestrels take small birds of all kinds, but only very occasionally.
My agent found a kestrels' nest in a church tower a fortnight ago which contained a quantity of bones of game and poultry.
