Signs of Spring Everywhere Update: March 1, 1999
Today's Report Includes:
In the middle of winter, newspaper carriers in Duluth, Minnesota (47.11, -91.85), work in the dark. Papers have to be delivered by 6:30 am, so carriers are outside by 5:45 or 6:00. In the past few weeks, they've been noticing the sky brightening by the time they finish, and now it's bright in the east by the time they start out. Sunrise today, March 1, 1999, is at 6:49 am in Duluth, so unless papers are late, carriers don't see the actual sunrise yet, but in a couple of weeks they'll be seeing the sun come up as they deliver papers.
What time is sunrise where you live? What day this month will your city have the exact same length of day as Duluth, Minnesota? (If you don't know when sunrise or sunset are where you live, you can find out here: worldwide sunrise times US sunrise times.) To learn more about how light affects animals, try Journey North's Seeing the Light lesson, also in the printed Teacher's Manual on page 93.
Birds don't deliver papers, but they also detect changes in daylight. Right now ducks are starting their journey north. Throughout the continent, birders are reporting the new arrivals. Wally Jobman is Journey North's correspondent from the Platte River of Nebraska, right smack in the center of things. He wrote, "As usual there were many overwintering Mallards along the Platte River, especially since it was an "open" winter without much ice or snow cover. Many pintails, shovelers, and teal are presently migrating across Nebraska. From my few observations, numbers appear to be normal."
Duck Watching Tips for This Week:
Usually our counts show more males than females. When nesting begins, that difference will get much bigger.
