Usually, individual birds infected with a disease develop an “immune memory” that is used to help protect them from reinfection. It’s similar to when your body creates antibodies after you get sick or receive a vaccine. The antibodies help prevent reinfection by that same pathogen strain. However, since birds can’t walk into vaccine clinics, their immune memories are not always perfect, and we’re learning about this phenomenon from House Finch eye disease.

Taking in the beautiful purple blossoms as the scent of lilac floats on the air seems like a pretty idyllic backyard setting, but new research shows that not all plants are equal. That pretty lilac, porcelain berry, fragrant bush honeysuckle, and ruby red Japanese maple in your yard might look nice, but non-native plants like these consistently have fewer caterpillars than native plants, according to new research published in July in Biological Conservation. And that means less food for birds.
“This article discusses several tried and true ways people remove lawn. From small patches to whole lawns–these techniques will get you started down the path to less lawn and more…pollinator flower beds? Trees? Shrubs? Veggie Garden? Your imagination is your only limit.”
Although most birds of North America are incredibly diverse, some species look very, very similar. One pair of species that look surprisingly similar are Hairy and Downy Woodpeckers.
