Great Spotted Cuckoos are an about dove-sized brood-parasitic species.
Both sexes look alike.
They have a silvery-grey crown with a crest which encompasses the
eyes with their red orbital rings. The sides and front of the neck,
together with the chin/throat, are cinnamon, while the nape of the
neck is black. The rest of the front, from chest to undertail coverts,
is off-white to light-grey.
The back and the wings are grey, with broad white tips on the wing
coverts that show as white bars on the folded wings.
The irises are dark-brown. The short, down-curved bill is grey with
a darker tip and the legs and feet are also grey.
The fact that the upper legs are covered by feathers ("trousers"),
like a raptor's,
gives the species its German name of "Hawk Cuckoo".
Juveniles
are black where
adults are
grey and they have rusty uppersides of their flight feathers that
show as rusty panels on the drooping folded wings.

Great Spotted Cuckoos are a partly sedentary, partly migratory
species found in parts of southern Europe, in Asia Minor and
in parts of the Middle East and of Africa.
They are sedentary in sub-Saharan and eastern Africa.
During the southern breeding season they extend their range into
southern Africa (except the south-western desert regions).
There are winter quarters are winter quarters in north-western
Africa and along the river Nile.
During the northern breeding season they extend their range into
parts of southern Europe, Asia Minor and northern Iraq.
Some birds are known to overwinter on the southern coastal fringe
of Iberia.
Apart from a small overwintering population in the South
of Iberia, n Europe Great Spotted Cuckoos are found as
breeding migrants only in the Mediterranean region.
Their range encompasses most of Iberia (except the far
North), southern France, the western coastal fringe of
northern Italy (except near the Alps) and an area in
Greece/Turkey near the Bosporus.
During the breeding season Great Spotted Cuckoos spend a
lot of time in the favourite habitats of their officially
listed breeding hosts, such as the
Iberian Magpie,
Eurasian Magpie,
or Carrion Crow,
in semi-open country with scattered trees.

J. Pires reports spotting a Great Spotted
Cuckoo in Mora, Evora, Portugal, in April 2014. Another was found
at Vila Franca de Xira, Tejo estuary, Portugal, in May 2020.
These locations are right on the north-western edge of the species'
range.

Note that, in general, cuckoos host on smaller birds.
However, the listed breeding hosts of the Great Spotted Cuckoo
are Iberian Magpies,
Eurasian Magpies,
or Carrion Crows,
which are the same size - or larger than - the cuckoo.
Therefore, it may be significant that we have observed a Great
Spotted Cuckoo being accompanied for a period of 15 minutes by a
Corn Bunting.
