Bird of the Week XXXVl











The last "Bird of the Week" is the Eastern Bluebird. It is not a common bird in Reading. As a matter of fact, I saw my first Bluebird in Reading in April of 2008. We just don't have enough of the necessary habitat to attract a lot of Bluebirds. The Male Eastern Bluebirds are vivid, deep blue above and rusty or brick-red on the throat and breast. Blue in birds always depends on the light, and males often look plain gray-brown from a distance. Females are grayish above with bluish wings and tail, and a subdued orange-brown breast. Blue tinges in the wings and tail give the grayer females an elegant look. Eastern Bluebirds sing a fairly low-pitched, warbling song made up of several phrases.
You can find Eastern Bluebirds in open country with patchy vegetation and large trees or nest boxes. Meadows, old fields, and golf courses are good places. Bluebirds typically sit in the open on power lines or along fences, with an alert, vertical posture. When they drop to the ground after an insect, they make a show of it, with fluttering wings and a fairly slow approach, followed by a quick return to the perch. Eastern Bluebirds eat mostly insects, wild fruit and berries.
Eastern bluebirds nest in cavities (holes). These holes may be in old trees, old fence posts, etc. They take readily to nest boxes erected in the proper habitat. The male Eastern Bluebird displays at his nest cavity to attract a female. He brings nest material to the hole, goes in and out, and waves his wings while perched above it. That is pretty much his contribution to nest building; only the female Eastern Bluebird builds the nest and incubates the eggs.
Eastern Bluebirds typically have more than one successful brood per year. Young produced in early nests usually leave their parents in summer, but young from later nests frequently stay with their parents over the winter.




The best place to see Bluebirds in Reading is at the Bare Meadow Conservation land off of Pearl St. Last spring a pair raised 3 broods (families)! A pair is nesting there this year and have all ready raised one brood.

Citizen Science Project - MOS FireFly Watch


The Museum has teamed up with researchers from Tufts University and Fitchburg State College to track the fate of these amazing insects. Pick a location, say your backyard, observe it weekly for 10 - 15 minutes, and report your observations online. For more information on how you can participate in this program, visit the Museum of Science FireFly web site.

Science Expo Day!

























































































































Today we celebrated all of the wonderful science we do here at Parker with our annual Science Expo Day. During this early release day, the entire school does nothing but science for the entire morning. Our Team designed and built 2-L soda bottle rockets. Unfortunately, due to the lousy weather, we weren't able to shoo them off. So, instead, we did 3 different activities. One, we built straw rockets and shot them off in the gym using air pressure. Two, we did a food nutrition label reading activity. And third, we built straw rockets powered by a balloon. Here are a few pictures of some of the things we did.

Bird of the Week - XXXV







This week's "Bird of the Week" is the Song sparrow. This small song bird is common here in Reading, perching out on a branch singing it's song. The Song Sparrow sings a loud, clanking song of 2–6 phrases that typically starts with abrupt, well-spaced notes and finishes with a buzz or trill. In between, the singer may add other trills with different tempo and quality. The song usually lasts 2-4 seconds.



Song Sparrows are medium-sized and fairly bulky sparrows. For a sparrow, the bill is short and stout and the head fairly rounded. The tail is long and rounded, and the wings are broad. Song Sparrows are streaky and brown with thick streaks on a white chest and flanks. The streaks come together to form a large, central spot. On a closer look, the head is an attractive mix of warm red-brown and slaty gray, though these shades, as well as the amount of streaking, vary extensively across North America. The Song Sparrow is one of the most familiar North American sparrows. They eat mainly seeds and fruits, supplemented by many kinds of invertebrates ( insects) in summer.
