River Bottom Ospreys and Songbirds

River Bottom Ospreys and Songbirds

* This kit is reserved in April / May / June for maximum one-week use by school classes in our 7th-8th grade Sandhill Cranes learning sequence.

(Grade 8) Osprey Biology PowerPoint, Learning Bird Songs PowerPoint, Art Projects, activities about songbirds and their river habitats. Preparation for a river-bottom field trip to do breeding bird surveys and Osprey nest observation. (Standards MS: LS1.A, LS1.B, LS1.C, LS2.A, LS2.B, LS2.C, LS4.C, PS3.D, ESS2.C, ESS3.C, ESS3.D)

1. Who am I?

            Using 17 laminated photos of local river birds, students play a game to try to match the bird with 17 sets of six or seven natural history facts about one of the birds. The facts start more general and obscure, and get increasingly specific.

                        Copies of “six facts” for above in binder

                        11 copies of booklet “Our Birds Call this Home”

2. Where is My Food Web?

            Students each “claim” one of the same birds from the previous activity, and           construct a food web of interrelationships between organisms in that food web. They then attempt to construct a web of interrelationships that have nothing to do with food, and introduce the concepts of mutualism, commensalism, parasitism and symbiosis.

                        (Same materials as above)

3. Water Pollution Dilution Solution?

            Students simulate a point-source toxin using a succession of clear glasses of water and food coloring, adding a small amount of water from each to the next one in line. Water in the last glass looks clean, but is it?

                        6 clear plastic cups

                        red food coloring

                        measuring cups

4. Ospreys: Ancient Fisher-birds scripted PowerPoint (on thumb drive in the trunk)

            A beautiful PowerPoint on the natural history of Ospreys. Teacher (or good oral-reader    student) reads the script (in the binder) and advances the images. 

5. “Concentrating” on River Birds

            Following up on “dilution” above, students do a math exercise with role-playing a simple food chain from phytoplankton to osprey. They use poker chips of Increasingly larger value to follow the “energy units” needed to sustain an osprey to breeding age. The  teacher shows the math in a long equation on the board as students use large-number calculators. (Phytoplankton produces ten units, and when done, the osprey needs about 10 quadrillion units.) Then the students are informed that they were really following molecules of DDT or other persistent toxins. A discussion of “bioaccumulation” follows.

6. Migration Highways 

            Using a series of large to small scale maps and a Cornell Laboratory of Ornithology         website, students draw likely migration routes for local riparian birds, identifying stopping places, food sources on the way, specific habitats they may be looking for (north-south mountain ridges, river systems, long valleys, etc.). They then discuss local opportunities to see this in action – Hawkwatch on Mt Aeneas, West Valley cranes, Lower Flathead waterfowl, winter waxwings in town.
