black ; primaries, edged with pale blue, the first and second 
row of coverts, broadly tipt with pale yellow; secondaries, 
broadly edged with the same ; tail, black, handsomely forked, 
exteriorly edged with ash ; the inner webs of the three exterior 
feathers with each a spot of white ; from the extremity of the 
black at the lower mandible, on each side, a streak of deep

under the wings, to the root of the tail ; the rest of the lower 
parts are pure white ; legs and feet, ash ; bill, black ; irides, 
hazel. The female has the hind head much lighter, and the 
chestnut on the sides is considerably narrower, and not of so 
deep a tint.

a plain chestnut ; till, on examining Mr Edwards’s coloured 
figure of this bird in the public library of Philadelphia, I found 
its side tinged with a brilliant blood colour. Hence, I suppose, 
originated the name !

I have now the honour of introducing to the notice of 
naturalists and others, a very modest and neat little species, 
which has hitherto eluded their research. I must also add, 
with regret, that it is the only one of its kind I have yet met 
with. The bird from which the figure in the plate was taken, 
was shot in the early part of June, on the border of a marsh, 
within a few miles of Philadelphia. It was flitting from one 
low bush to another, very busy in search of insects ; and had 
a sprightly and pleasant warbling song, the novelty of which
