Today I biked out early and watched, at an Undisclosed Location, a couple birds singing. Okay, it happens every day, but these particular birds were two that are only found in Madison during migration (they breed farther north) and whose songs I am not very familiar with: Lincoln's Sparrow and Philadelphia Vireo. Seeing these two vocalize was the high point (thus far) of my day, much more so than seeing Sandhill Cranes, a Great Horned Owl, a male Wood Duck and a male Eastern Bluebird.
You don't have to get up at 4:20 to see/hear such things...as you might find out this weekend on any of my guided, by-bike field trips. Please drop me an email for details...firstname.lastname@example.org
