Recorder or shawm?
Admitedly, it is hard to tell just from the picture (and also hard to tell if we're all looking at the same picture). She does mention on her website that she plays recorders as well.
However, I think the instrument pictured in the first URL is probably
not a recorder, for two reasons. First, the bore of a recorder tapers from head to foot. Some do have a faux bell, but this is not hollow: there is only a small hole for the bore, and the rest of the "bell" is solid. This instrument appears to flare from top to bell, and the bell appears hollow.
Second reason is the way it is miked. The recorder is a
very quiet instrument, softer than the flute. Most of the sound emanates from the window (between the mpc and the fingerholes: this is where the edge divides the air flow and produces the tone). When you mike a flute, you position the microphone close to the embouchure hole, rather than off by the foot. Same thing with recorder. If she were playing recorder, she would be holding it nearly vertically, with the window as close as possible to the microphone (given the context of a loud rock band). Here's an example of
miking a recorder. Instead, she is standing back a few feet, and has the bell pointed directly at the microphone. This is how you mike something that is as loud as a trumpet ;-) The shawm was considered an "outdoor" instrument: about the only thing louder is the rauschpfeife (OK, and highland pipes).
Enjoy,
