This week will begin the juveniles seventh week from hatching. It looks promising that the two will fledge and take their first flights soon. Last week we noticed Jasper fly in and take the fish that Bea was feeding their offspring, most likely encouraging AT and HT to take flight.
Notice the semi-transparent lens in the second to last photo. This is the nictitating membrane which keeps their eye moist and clean and they use it while diving into water to catch fish.
