Bees and birds and a wedding

Yesterday (20th), we learned about pollinator foraging behaviours and the techniques they used when visiting different type of flowers and inflorescence in order to maximize their gain and minimize the loss.  We also began brainstorming about our field projects, and another student and I were thinking of teaming up to study what are the effects of ants on stigma receptivity and pollen germination.

This morning was a lecture on abiotic pollination - wind and water.  In the afternoon, we were off to the botanical garden to bag some flowers and start on our project.

Saw some American Goldfinches taking a bath from this stream.

As I was walking home, I saw this Eastern cottontail rabbit (Sylvilagus floridanus) trapped on the same side of the fence as I was in.  I took some photos before stepping in the opposite direction and letting it ran free.  They are considered a pest in the botanical garden.

Then I heard strange calls.  Looking up, there were two male Brown-headed Cowbirds (Molothrus ater) and one female on top of me.  Probably courting the female or something.

Tomorrow we get a day off.  Looking forward to do some exploring of downtown St. Louis.
