“On our recent trip to Taiwan, my bird guide and me were comparing the calls of my favourite ball of feathers, the Collared Owlet (Glaucidium brodiei). The Taiwanese Collared Owlet call was slower, and more mellow, while the one I have from Malaysia’s Fraser’s Hill was faster and sharper. So I tried using my Fraser’s Hill Collared Owlet call to see if I can get any reaction – absolutely no response, they just ignored it.
“So from this little experiment I guess that there are variations in calls for the same type of birds in different countries. Just like the Chinese diaspora, hokkien, cantonese, teochew, hakka, etc.”
