- The suggestion that the Hooded Pitohui's coloration evolved to advertise
- their toxicity seems dubious to me. Their coloration didn't look that striking
- (in the picture on the cover of Science), especially for a New Guinea bird.
- Other (presumably non-toxic) members of the same family are much more
- striking than the Hooded Pitohui e.g. Crested Shrike-Tit (monomorphic),
- male Golden Whistler (dimorphic, female is drab).
-
- It'll be interesting to find out if predators recognise Hooded Pitohuis
- by sight (they also have a strong odour).
