The dawn chorus in my urban neighbourhood has changed in composition.
Instead of the audio feast generated by the many Yellow-vented Bulbuls (Pycnonotus goiavier), I now get the harsher callings of the Red-whiskered Bulbuls (Pycnonotus jocosus). The Yellow-vented Bulbuls are still around but they are in the minority.
The timing of the dawn chorus remains more or less the same, beginning at around 0645 hours and continuing for about 20 minutes or so.
The invasion of the Red-whiskered Bulbuls into the neighbourhood has mostly displaced the Yellow-vented Bulbuls LINK. This comes with a visual treat, not so an audial feast.
