Black-bellied Plover

Black-bellied Plover (Winter plumage)

The Black-bellied Plover migrate to winter in coastal areas throughout the world. In the New World they winter from southwest British Columbia and Massachusetts south to Argentina and Chile, in the western Old World from Ireland and southwestern Norway south throughout coastal Africa to South Africa, and in the eastern Old World, from southern Japan south throughout coastal southern Asia and Australia, with a few reaching New Zealand. Most of the migrants to Australia are female. It makes regular non-stop transcontinental flights over Asia, Europe, and North America, but is mostly a rare vagrant on the ground in the interior of continents, only landing occasionally if forced down by severe weather, or to feed on the coast-like shores of very large lakes such as the Great Lakes, where it is a common passage migrant.

Peruvian Boobies have relatively low wing loading, and are considered glide-flappers, meaning they alternate active flapping with short periods of gliding. Because of their wing morphology and style of flight, they have a preference of flying across the wind, as opposed to flying with a tailwind or headwind. This is beneficial because it requires less energy than flying directly into the wind, while it results in a higher prey encounter rate than flying at high speed with a tailwind.
The average speed of the Peruvian booby is approximately 44 km/hour, however they have been seen to be able to fly at speeds up to 139 km/hour.

  1. Great to see both these birds today, HJ, and learn interesting info about them. The Black-bellied plover is such a worldly bird, and the Peruvian Booby’s flying skills are impressive. Thank you, my friend.

    • The Peruvian Booby’s is famous because before the WW1 it made Peru very rich, most countries in the world needed the nitrate to make gun powder and this bird gave them the most concentrated nitrate, urea and phosphorus fertilizer in the world. Even now, 50 Lbs will cost you $100, being the best fertilizer you can get for agriculture. Most small islands in Peru are being mined. (Hundreds of years of sediments) The Incas used this for their crops.
      Thank you, Jet for stopping by. πŸ™‚
