“‘kroo,” with a good roll on the r, would describe the note tolerably 
well. Each time the bird makes this noise (which is about two

he started.”

Lower Caffraria, and we know of only two other specimens besides 
the typical ones in the Stockholm Museum, viz. a pair in the national

tail black, glossed with greenish above and just tipped with white; 
sides of face and pectoral band rifle-green; rest of under surface
