Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight. 
Explanation:
The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.
Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes  
Birds soar by using thermal and dynamic soaring techniques.
Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.
The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.

Answer:
Hummingbird
Explanation:
Pollination is the process by which pollen grains are transferred from anther of a flower to stigma. It is a vital process required for reproduction of new plants. 
Cardinal flower has two upper petals and three lower spreading petals. All the petals combine to form a tube at the base. Hence the flowers get a tubular shape. Insects can not enter the tubular flower easily so humming birds usually pollinate these flowers. The hummingbirds feeds on its nectar and pollinates the flower in the process.
