When I looked out my back door today something was bobbing up and down on our back lawn. I thought at first it was a ground hog but looking through the binoculars I saw that it was a bird but one I have never seen before. Unfortunately it flew off when I opened the door to try and get a picture. Google search told me that it is a Gila Woodpecker. It is a long way from home and must be hating this cold which is probably why it was sunny bathing on my lawn.
Carol, we don't have Gila Woodpecker in NB but we do have one similar, Northern Flicker. I would suggest that was the bird you noticed on your lawn. They are ground feeders although you can see them in trees at times; their favorite food is ants.
There are 2 species of Northern Flicker in Canada, the one we have in the eastern areas is Yellow-shafted, the one seen in western regions is Red-shafted.
