Northern Gannet

June 6, 2018, Cape St Mary's, Newfoundland.
Amazing wingspan of up to 6 feet. Morus bassanus
Their eyes have special structural adaptations for plunge-diving, and they are able to see well underwater immediately after striking the water.
Most plunge-dives are relatively shallow, but the Northern Gannet can dive as deep as 72 feet. It uses its wings and feet to swim deeper in pursuit of fish.

Zonotrichia albicollis White-throated Sparrows typically nest on or near the ground. Occasional nests are built up to 15 feet off the ground in conifers. Usually, these nests are second attempts after a pair has had a ground nest robbed by a predator. source - Cornell lab of Ornithology.
