Drawing makes you look at the details. You can't draw each detail, but you are picking out the exact form, the shades of color that identify the bird. Drawing made me not only look at the bird, but at the twig it was sitting on, that the twig had growths on it, that some of the leaves were damaged and eaten. Drawing makes you look at all the details, instead of just writing that the bird is a yellow warbler.
I have always been interested in the natural world. For years I have kept a written journal about what I have seen on walks and trips. Due to work and family responsibilities, the input was very limited. Now that I am retired I would like to expand that input and include drawings and hopefully eventually water colors. I hope this will improve my observational skills.
I was impressed by all the journals presented. I especially liked the drawings of the spider consuming the bee and all that the drawer learned from observing it. I also liked the hummingbird drawings and how the presenter was trying to show all the different body movements in her drawings. I was impressed by how much talent all the presenters had.
