What, you again?
These young ladies are in a nature course at a local private college. They were doing a timed study of which will be consumed faster- Safflower seed of Shelled Sunflower seeds. They didn't bring plates so had to improvise and place the seed on car mats. This was much to the displeasure of the one with the hat who owned the car. She wasn't real happy with all the waste in this feeding area. I was bursting with information, but kept it to myself. Right now a few species are ground feeding that wouldn't normally in warm weather and the safflower dissuades squirrels, but some species don't care for it. I love research like this, and have joined in on many small projects. My guess is their first stop after leaving was to a car wash to wash those mats off. LOL They weren't real interested in the Pileated Woodpecker I sighted coming toward this area as I hike this beautiful state park looking for them. Well good luck on the education, and experience found out on the prairie.
I am going birding and a good early morning hike.
Six species is a slow day, but it was fun.
