Definitely, Pacific Cycles built. They seem to be US warehousing a limited selection of models (City, Touring, GT) in a single color per model. Still, more available than just a few years ago when one had to write a letter of inquiry to an old guy who might still be in business.
The only Birdy I've ever seen IRL in the US was on a big LBS sales floor back when the (now defunct) Burley company was the distributor - hmm, maybe 1997?
