The great kiskadee (Pitangus sulphuratus), called bem-te-vi in Brazil, pitogue in Paraguay, benteveo or bichofeo in Argentina and Uruguay, and luis bienteveo, pitabil, luis grande or chilera in Mexico, is a passerine bird in the tyrant flycatcher family Tyrannidae.

The great kiskadee was described and illustrated in 1648 by the German naturalist Georg Marcgrave in the Historia Naturalis Brasiliae.

[5] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.

[6] When the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition in 1766 he added 240 species that had been previously described by Brisson in his Ornithologie.

Linnaeus included a terse description, coined the binomial name Lanius sulphuratus, and cited Brisson's work.

[5] The great kiskadee is now the only species placed in the genus Pitangus that was introduced by the English naturalist William Swainson in 1827.

The similar boat-billed flycatcher (Megarynchus pitangua) has a more massive black bill, an olive-brown back, and very little rufous in the tail and wings.

[16][17] The great kiskadee occupies a wide range of habitats, from open grassland with scattered trees to urban areas.

It is almost omnivorous and hunts like a shrike or flycatcher, waiting on an open perch high in a tree to sally out and catch insects in flight or to pounce upon rodents and similar small vertebrates (such as other birds' chicks and bats).

[21][22] It will also take prey (such as small snakes, lizards, frogs, perched insects, spiders, millipedes and land snails) and some seeds and fruit from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for freshwater snails, fish or tadpoles in shallow water, making it one of the few fishing passerines.

[26] Kiskadees like to hunt on their own or in pairs, and though they might be expected to make good use of prey flushed by but too large for the smaller birds of the understory, they do not seem to join mixed-species feeding flocks very often.

[15] This alert and aggressive bird has a strong and maneuverable flight, which it uses to good effect when it feels annoyed by raptors.

Even omnivorous mammals as small as the common marmoset (Callithrix jacchus) will try to plunder great kiskadee nests – at least during the dry season when fruits are scarce – despite the birds' attempts to defend their offspring.
