Bourcieria boliviana

Bolivian Inca

Illustration not included in supplement volume

This bird, which comes from Bolivia, bears a general resemblance to B. cœligena, but differs in being of a much darker colour on the head and neck, and in having the tail dark olive-brown washed with bronze in lieu of light bronzy brown.

The lower part of the back also is more richly coloured, the crescentic markings of green showing still greater lustre when viewed from behind. Total length 5\(\frac{1}{2}\) inches, bill 1\(\frac{1}{3}\), wing 3\(\frac{1}{4}\), tail 2\(\frac{1}{8}\), tarsus \(\frac{1}{4}\).
