Move over owls…
Domed nests, like the one in the newspaper clipping, were once thought superior to open ones. The conventional wisdom was they offered better protection from predators and harsh weather. Turns out, a roof over their heads really isn’t good for songbirds. The fancier and more complicated the dwelling, the less robust the dweller. Domed houses are correlated with smaller ranges and fussier climate needs- maladaptations. A simpler nest is better.
I’m not suggesting you take the roof off your house, but it might be worth thinking twice about fancy and complicated. “Progress is man’s ability to complicate simplicity.” Thor Heyerdahl, a Norwegian adventurer and ethnographer with a background in zoology, botany and geography.
Complicating simplicity? Birdbrained.
