They should be able to see the red light - I don't know about Mynas but
birds generally have more elaborate color vision than we do.  At least
in Sydney, red traffic lights switched some years ago to LEDs.  Its an
application LEDs are particularly well suited reducing power consumption
by 5-10x and with significiantly longer long lifetime.  An unintended
consequence could well be 5-10x less heating of a Mynah nest.
