Note: These Challenge Questions coincide with the Spring 2006 Reports Challenge Question #1 From: by way of Jane Duden Journey North <ardaghy@eircom.net> Date: Sat Mar 11 2006 - 21:31:46 EST We think that the variables are the availability of food such as berries.

The American Robin Group Ardaghy National School ages 9-12 We have robins in Ireland and they stay all year as our weather is never too cold although we get some snow. Our robin is smaller than yours and the colour is different. Received on Sat Mar 11 21:31:49 2006 Copyright 2006 Journey North. All Rights Reserved.
