Patterns of Spring

Since we settled here, we’ve been keeping records of natural events like bird migrations, flower bloomings, and so on, with the goal of documenting and better understanding the natural patterns here. Spring is one of the best times to appreciate these records, as so many new things are happening and arriving. So far, our general observations suggest that migratory birds are on about the same schedule as last year, but wildflowers and local animals are behind. This makes sense, as last spring the weather was abnormally warm here, so that local flowers bloomed early, but birds respond to large factors than local weather.

Anyway, here’s a few glimpses at the changes (or not) since last year:

Birds (first observation in 2007, 2008):
Woodcocks: 2/27, 3/6
Louisiana waterthrush: 3/26, 3/26
Phoebe: 3/11, 3/13
Towhee: 3/11, 3/19
Snow geese: 3/22, 3/23

Other animals (first observation in 2007, 2008):
Spring peepers: 3/8, 3/1
Young snake (prairie king snake?): 3/28, 3/26
Box turtles: 3/13, none
Bats: 3/13, none
Ticks: 3/28, none

Wildflowers (first observation in 2007, 2008):
Crocus: 3/4, 3/10
Harbinger of Spring: 3/13, 3/19
Redbuds: 3/27, none
Spring Beauty: 3/25, none
Bloodroot: 3/25, none

Soil temperature 6″ down (2007, 2008)
February 25 (32, 32)
March 10 (40, 36)
March 24 (none, 40)

These sorts of data will be even more valuable in years to come as we build a meaningful record of long-term patterns, but even now they’re fun to peruse. Keeping a simple notebook is relatively easy, and the rewards are quite meaningful.
