Blue Jays and Bluebirds - Outdoor Hour Challenge

This week as part of the Outdoor Hour Challenge, we read about Blue Birds in the Handbook of Nature Study by Anna Botsford Comstock and and Blue Jays in Birds of Minnesota Field Guide by Stan Tekiela.

These are some of the facts we learned about these birds include:


=> The red breasts of these birds brought to memory the robins of England, and so they were called "blue robins."

Birds of Minnesota Postcard
Postcard I had that features different songbirds of Minnesota.
The bluebird is in the lower right-hand corner.

=> Bluebirds and robins are both members of the thrush family, a family noted for exquisite song.

=> Singing ends with the hard work of feeding the nestlings. However, it can be heard again as a prelude to the second brood in June.

=> The cerulean blue of the bluebird's head, back, tail, and wings is most brilliant when it is flying in the sunshine.

=> The female is paler, being grayish blue above and with only a tinge of red-brown on the breast. Both birds are white underneath.

=> Bluebirds like open woods, fields of second growth, and old orchards.

=> When feeding, the bluebird usually sits on a low branch keeping a watchful eye on the ground below. Now and then it will drop suddenly on an unsuspecting insect and then return to its perch. It doesn't stay on the ground hunting for food as does the robin.

=> The nest is usually built in a hole in a tree or post and is made of soft grass.

=> The food of the nestlings is almost entirely insects.

=> Bluebirds migrate during the autumn, and winter in the Gulf states.

=> Bluebirds are different from the indigo bunting, the latter of which is a darker blue and has a blue breast.

Blue Jays:

=> Blue jays are about 12 inches in length.

=> They have light blue and white feathers with a black necklace. The belly is gray. The males and females look the same.

=> The crest moves up and down at will.

=> Both the female and male construct the nest; and there are 1-2 broods per year.

=>  There are 4-5 green to blue eggs with brown markings.

=>  Incubation is 16-18 days; and the fledging stage is 17-21 days.

=>  They do not migrate south. Rather, they will migrate only from location to location to find a more abundant food source.

=> They like to eat insects, fruit, carrion, seeds, and nuts. They will visit feeders; and especially like ground feeders with corn. They will scream like a hawk to scare birds at a feeder.

=> Blue jays are highly intelligent, can solve problems, gather food, and communicate more than other birds.

=> They will scream at intruders in the woods.

=> The blue jay is one of a few birds to cache food.

Outdoor Time

We spent time outside, but didn't see any blue jays or bluebirds. The blue jays, however, were in the pine trees and calling to one another. They have a very distinctive and easily-recognizable sound.

On October 2, 2012, we saw a family of five bluebirds at the bird bath. The water was a bit low, so Olivia went out and put a pitcher-full of water in the bird bath. Hopefully they will visit the bird bath again soon.

The girls were able to see bluebirds on a birding hike in May 2012. The local state park offering an evening walk, and there were two bluebirds perched on a sign.

The group stood back and observed the birds. Once the birds flew away, we continued on the walk.

Nature Journaling

Both Sophia and Olivia did an entry in their nature journals.

 The girls each included images of the birds as well as facts they wanted to remember.

Did Sophia draw the bird in her journal? If so, she is very good at drawing birds.
