Nature by the yard

  Oodles of orioles and a gross of grosbeaks flocked to my feeders. Greedy beaks consumed food. Migrating at night, they are cold, tired, and hungry upon arrival. Baltimore orioles feed mostly on the nectar of tree flowers until the caterpillar and insect populations grow. They like fruit and nectar, so they can be attracted with orange halves, grape jelly, and sugar water in oriole or hummingbird feeders. They also will eat mealworms, suet, and nuts.

Falling for birds

  A friend was in his eighties. He was a rare bird, one that was always a delight to see. He maintained a number of wood duck boxes that required a long ladder to get to the boxes. One day, he was out checking the wood duck boxes. He lost his balance and fell from the ladder. Other than minor bruises and a dented ego, there were no injuries. His kids took his ladder away.

Towering pines make it difficult not to be humble.

  I took my camera for a walk and photographed a migrating bufflehead swimming about. A knucklehead watching a bufflehead seemed appropriate. Buffleheads breed near ponds and lakes in boreal forests and aspen parklands of Canada and Alaska, with isolated populations in the US. The bufflehead’s breeding range is limited by the distribution of northern flickers, which are their main provider of nesting cavities. Buffleheads are North America’s smallest diving duck and the old flicker nests are too small for goldeneyes, wood ducks, and mergansers.

Honors for Bill Bryson 

  A good friend, Bill Bryson of Alden, was inducted into the Minnesota Waterfowl Association Class of 2014 Hall of Fame at their February annual banquet. Tom Tubbs presented the award.

Q-and-A

  "Will yellow-bellied sapsuckers kill trees?" Yellow-bellied sapsuckers drill in many species of trees, but have a strong preference for birches and maples. As their name indicates, sapsuckers rely on sap as a main food source. Just as people tap maple trees to make maple syrup, sapsuckers drill wells in spring. The birds first drill narrow, circular wells into the tree’s xylem, the inner part of the trunk, to feed on the sap moving up to the branches in early spring. Then, after the trees leaf out, the sapsucker drills shallower, rectangular holes in the phloem, the part of the trunk carrying sap down from the leaves. The phloem wells must be continually maintained with fresh drilling, so that he sap would continue to flow. The sapwells attract hummingbirds, which also feed on the sap flowing from the tree. In addition to sap, yellow-bellied sapsuckers also eat insects, spiders, and fruit. The shallow damage shouldn’t cause serious problems to a healthy tree. If you are concerned about a persistent sapsucker causing injury to a tree, wrap hardware cloth around the affected area.

  "Why are robins’ eggs blue?" Maybe blue is more difficult for predators to see than a white colored egg. Or a brood of blue eggs might make it easier for the mother to spot an egg that doesn’t belong, like that of a parasitic-nesting cowbird. It’s a mystery.  A good number of other birds have blue eggs.

  "Where do sandhill cranes nest?" The three subpopulations of sandhill cranes are migratory. The lesser, greater, and Canadian sandhill cranes spend winters in the south and summers at their breeding grounds. The largest congregation of migrating sandhill cranes occurs from February to early April along the Platte River in Nebraska. Some breed in Minnesota, Wisconsin, Michigan, Oregon, Idaho, Alaska, Canada, and Siberia.

Nature lessons

  The bite of a tarantula is typically no worse than that of a wasp or a bee.

  Centipedes are distinguished from millipedes in having one, not two, pair of legs attached to each segment.

  A plague of locusts swept across the American West in the summer of

1875. The size of that swarm was estimated at 198,000 square miles--bigger than California.

  Bergmann's Rule states that a species is larger in size in colder environments and smaller in size in warmer regions.

  Dutch researchers have created a bladeless wind turbine with no moving parts that produces electricity using charged water droplets.

  A group of waxwings is collectively known as an "earful" or a "museum."

  In golf, a score of three under par on a hole, one less stroke than an eagle, is called an albatross.
