If you look into included photos, you'll see the killdeer catching what I think are fly larvae. It will apparently wash the mud off before swallowing. Notice the water droplets flying as the subject shakes its prey after immersion.
Something's clicked recently with getting a lot of these out in the field. Thank Jesus!
