ZEBRA DOVES - 13. Nearly a month and still they need mummy.

The older of the fledglings is now 28 days old. The parent bird arrived this evening, perched high up on a nearby building and cooing a few times to attract the fledglings. After an initial period of greetings, the birds flew straight to a nearby tree. They spent some time moving from branch to branch foraging(?) before they settled on a nearby tree for the night. Apparently they must have come back to the same area every evening since fledgling, spending the night together before flying off early next morning. The mate must be around as there was a call from elsewhere. How long more will it take before the fledglings become independent???
