This very rare species - osprey flycatcher - can be seen in photo #7.
Ospreys are constantly building up their nest. In #3, male osprey is bringing a stick to the nest while the female is still sitting on the eggs. Once the babies hatched, the male switched to mostly hunting while the female would get a couple of sticks or some grass after every meal. Some sticks fell to the base of the nesting platform but she never picked them up and preferred to fly to distant dead trees; she must be wired to avoid possible predators on the ground.
