I have two bluebird nests in my back yard, and two at the land I own. Bluebirds have been busy building nests in all four of them the past few weeks and I think the females will lay eggs soon. I have enjoyed watching the pairs of birds working back and forth constantly this spring.
It is amazing how bright blue the male bird is this time of year. It brightens up to attract a mate in early spring and will keep the deep blue color for a few weeks, gradually fading to a lighter color as the summer progresses.
I have also enjoyed watching the Canada geese on my two small ponds. I build nesting platforms from them, making a small raft for them to nest on. A female is hard on the nest, not leaving very much at all, on one of the ponds, a good sign she has started laying eggs. A pair on the other pond have not started laying eggs yet.
About a month ago nine geese moved onto the bigger pond. They would fight and honk at each other constantly, trying to establish dominance. Finally one pair ran the others off and claimed that pond as their own nesting site. One lone goose went to the upper pond and stayed there, and the other six left for parts unknown.
That single goose stayed around by itself for a few weeks and now it has gone. As soon as it left, a new pair moved in. I hope both pairs are able to raise some young this year.
Pay attention to the birds around you this spring. They are entertaining as well as educational.
