A couple of years ago I started to notice an unusual (to me) bird in our alpaca pastures. It made a lot of noise and did more running around on the ground then flying. I grabbed my Missouri bird book and discovered the Kill Deer. They have very distinct markings so they are easy to identify. I then discovered that they lay their eggs on the ground, usually amongst a small cluster of rocks. They don’t build a nest; just lay them in a hollowed section of the grouping. The eggs are almost the same color pattern as the rocks so you have to really look to find them.
The problem with laying eggs in the alpaca pastures is that the alpacas are continually moving around the pasture grazing. Usually the older alpacas will avoid the eggs but the crias (baby alpaca) haven’t figured that out yet. As the crias are exploring and romping around the pasture they sometimes get too close for momma bird’s comfort. When this happens a series of events and antics begin.
One of the birds, they usually guard the eggs as a pair; will start making a lot of noise to sound the alarm. She/he is probably screaming, “Get away from my nest!” Of course alpacas don’t speak Kill Deer so they haven’t a clue what is being said. The crias think the bird wants to play so they are more than willing to participate. The bird will try to draw the cria away by leaving the nest in hopes that she will follow. If that doesn’t work then the second diversion is started. The Kill Deer will spread out its wings and tail feathers, revealing a yellow coloring, meant to draw attention to itself. As the cria draws closer the Kill Deer will keep moving away from the eggs. The third diversion is known as the “broken wing” scenario. The Kill Deer will throw one wing out to the side and flap it as if it were broken; demonstrating that it is an easy prey. Again as the predator – cria – approaches it moves farther away.
I was taking a break from chores and noticed one of our new crias, Quibble, encountering one of these nests. Knowing what was to follow I watched the process with a grin on my face. After several minutes the cria finally lost interest and moved back to the herd. I am sure the Kill Deer was relieved and a little tired of the whole thing.
Nature has such a wonderful way of protecting itself. Sometimes it provides comic relief to the spectator as well.
