Female incidentally caught in raptor nets. Female didn't vocalize. Concerning Types... the following from Matt Young: "As for measurements, I almost entirely only look at bill depth to type birds, it's the most heritable and not influenced by what time of year if they're fattening up or by wear depending on what they're feeding on. Wing chord can be useful too, which makes these measurements a bit interesting. The male is definitely a Type 3 with 7.8 bill depth though. The female is either a large Type 4 or a smallish Type 2, I'd hedge Type 4." Female (presumed AHY/SY? by molt limits and plumage coloration): wing 92mm, weight 36.2, nares to bill tip 15.6mm and depth 8.95mm, missing outer 3 rects on right side. P9-1 uniformly new; all secondaries old; primary coverts new except innermost on right wing retained juvenile; all greater coverts uniform age; rects uniform and broad-tipped.
