Naturally

It was cold enough to foster all kinds of second thoughts.

Sooner or later, it will defrost.

Still, the day seemed enchanted. They all are.

A sun dog rainbowed down, appearing to rest upon a wind turbine.

Q-and-A

"Does a purple martin really eat 2,000 mosquitoes per day?" I wish it did. Mosquitoes account for, at most, 3 percent of its diet. Purple martins prefer larger prey such as dragonflies and damselflies.

"Goldfinches look different during the year. Why?" American goldfinches molt twice a year. They have bright yellow feathers in the spring before breeding and olive brown feathers in the fall. The color of their legs, feet, and bills change with the feather molt. In winter, they are a dark-grayish brown. In breeding plumage they are a buffy yellowish-orange color. American goldfinches are partial migrants, meaning only part of the population migrates annually. Winter can cause them to become nomadic and they may move farther south to find food.

"Most of the juncos in my yard appear to be males. Why is that?" Dark-eyed juncos have gray or brown heads and breasts set off markedly from white undersides. Females and immatures are rather browner than adult males. Males are typically darker with sharper markings. Females have more indistinct markings. Most juncos are migratory, following the food supply south. Males winter farther north than females. There is a social hierarchy within the winter flocks. Males tend to be dominant over females and adults are dominant over younger birds. Because males are dominant, females have less access to food and tend to winter away from the males. Males risk harsh winters farther north in order to be closer to the breeding grounds. Females don’t compete for territories in the spring and take their time returning. When encountering another junco, the bird faces the other, raising and fanning its tail, and revealing white outer tail feathers.

"Do house finches migrate?" House finches may be confused with purple finches. Purple finches have a more reddish color on their upper parts and are not streaked on their abdomens. In groups, house finch males and females usually establish dominance hierarchies, in which females are typically dominant over males. Throughout most of their range, house finches don’t migrate. However, some populations in the north move south for the winter. Some of those migrations are of short distances.
