The most notable characteristic of the Ruffed Grouse isn't how they looks -- it's how they sound. In the spring and a little in the fall, the male ruffed grouse beats the air with his wings to make a loud drumming sound.
expired test strips are NOT reliable. most strips have an expiry date over 2 years from the date of manufacture...... that's a long time for them to be 'sitting around'. as for e-bay........
Test strips typically have a 24-36 month shelf life. Look on container bottom for expiry date. Store reagents and test strips in a cool, dry location, out of direct sunlight. Take your water sample or dip your strip under the surface, so as not to test surface water.
