Last,Wednesday, January 25, 2017, Mr.Evans from Birds Of Prey and The Peregrine Fund came back to our school for another visit. This time he brought a Swainsons Hawk named Griffin. Griffin is a female Swainsons Hawk. Griffin migrates south during winter to Argentina and Brazil to survive because Idaho does not have as many bugs as Argentina and this is mainly what Swainsons Hawks eat.

Griffin has adaptations like all predators who are raptors. One of her adaptations is a very long  wingspan. Her wingspan is about three feet long; it's almost as tall as me! Just joking. Her large wingspan is to help her catch her prey easier.

Before Mr. Evans left he showed us a chart and discussed research about not getting enough food near roads. The study examined if this might be because road noise may affect the birds. Birds were netted in an area with no noise and others were netted in an area that had speakers installed playing recorded road noise (there was really no road, it was called a phantom road). The birds netted in the area with speakers had less fat on their bodies than the birds in the area with no road noise. It was very interesting to learn about this type of research!

We are very excited for the next time Mr. Evans visits our school! Thank you.
