I recently came across this description, in Wikipedia, of the Pin-striped tit-babbler;
“The species has a distinctive yellowish supercilium and rufous crown. The throat is yellowish with brown streaks. Call is a loud repeated chonk-chonk-chonk-chonk-chonk somewhat reminiscent of a Common Tailorbird.”
This similarity of calls must be a source of constant irritation to the Pin-striped tit-babbler as there is clearly a pronounced class difference between it and the Common Tailorbird.
Pin-striped tit-babbler – note the discreet flecking, the aloof expression
Common Tailorbird – cocky stance, garish décor
On the rare occasions the two interbreed an interesting hybrid occurs;
Pin-striped Tailorbird – he's never sure whether the milk goes in before or after the tea
