IN the Appendix to Pennant's British Zoology, a figure 

 and short description are given of this bird, under the name 

 of " the Rough-legged Falcon ;" and in the Arctic Zoology 

 of the same author, the bird described as the " Dusky Fal- 

 con" appears to be very safely referable to the same species. 

 By many ornithologists the Falco pennatus, a bird belong- 

 ing to the first or Aquiline section, has been confounded with 

 this species, to which it bears a close resemblance, both in 

 size and colour. It may, however, be readily distinguished 

 by the form and size of its bill, and the uniform brown co- 

 lour of the tail, which, in the bird now under description, is 

 always more or less white at the base.
