Tengu

Tengu are feathered humanoid creatures with bird-like heads and beaks. Found around northern Kryta as Caromi Tengu and in the Shiverpeak Mountains as Avicara, they are quick-moving and dangerous. Sometimes humorously referred to as 'Hens'.

Caromi Tengu are met all around Kryta and are fairly strong, especially as their fast movement makes killing their mesmers pretty tough, their scalps are often used at the event-specific collectors in Lion's Arch

The vast majority of the Avicara bosses are located in Mineral Springs. They are often used as cannon fodder fighting the Titans during the Defend Droknar's Forge quest (surprisingly being able not only to withstand them but also defeat them).

Interestingly, "tengu" in Japanese folklore are a type of kami (roughly "spirit") described as "crow-headed humanoids" with "beaks... sometimes lined with sharp teeth." See Wikipedia's entry on Tengu. See also: Category:Tengu.
