Puerto Rican tanager

Ever thought you were going deaf when you can see the beak of a bird moving but you can’t hear the sound? Well here is a bird that calls high up there in the frequency scale, The Puerto rican tanager (Nesospingus speculiferus) The Puerto rican tanager is a small passerine bird endemic to the archipelago of Puerto Rico. It is the only member of the Nesospingus genus of the tanager family. The sound available here is the very high 12 KHz calls, if you can’t hear it you either have wax in your ears of your aging fast :)
The tanager is reasonably common in mixed-species flocks in the humid Puerto Rican highlands, this was recorded in the Caribbean national forest.
