Winter flocks have come together. Concentrated further with each snow storm we get chickadees, cardinals, bluejays, juncos, nuthatches and titmouse; give yourself a ringside seat by putting out a birdfeeder this winter.

Trees and animals depend on each other for their mutual survival. Acorns, pictured here, have a protective package on the outside, allowing them to be safely transported, some eaten, some buried to sprout elsewhere.

”Blackbird” flocks can be seen any time of day this time of year, sometimes in tight blobs of shape shifting flocks called ”murmurations” like this one at the most common time to spot them, around dusk.

No, this isn’t a pile of sprouting chia seeds — it’s sporulating moss, stimulated by the recent rains.

Young oaks tend to turn redder than fully grown oaks this time of year, as is evidenced by this particularly red young red oak tree.

Asters such as this silver aster continue to bloom white, lavender and purple as the primary remaining fall flower. The prairie grasses will continue to get richer in color.

The beautiful blue petals of the gentian are gracing some prairies this time of year.

Some people get confused between poison ivy and virginia creeper this time of year because their leaves both turn red. But virginia creeper has blue berries; poison ivy’s are white.
