Hi everyone, Go birding this weekend! The weather forecast looks excellent for a big push of migrants, and there might even be a chance to hear night migrants if you happen to find yourself in the right place at the right time. If you haven't already heard of the BirdCast project to forecast bird migration events, check out the newly launched website http://www.BirdCast.info/. Here's their forecast for this weekend into next week: "*Upper Midwest and Northeast* Warm moist air continues to prevail from Maine through the Ohio River valley, keeping migration primarily light and scattered. However, a change is on the way, with the western Great Lakes and upper Mississippi River valley feeling the effects of a passing cold front and a strong area of low pressure to the north. In areas to the west of this system’s passage, movements will be heavy and locally very heavy. Birders in these areas should watch carefully for landbird and waterbird fallouts, as rain associated with the passing front will put down birds where it passes. As this system moves east to end the weekend and begin the week, favorable winds will overspread much of the region, spawning heavy movements and some locally very heavy movements. These conditions continue through the beginning of the week, gradually becoming more marginal as the system moves into the Atlantic. By Tuesday, areas east of the Appalachians continue to have favorable conditions with continued moderate and heavy movements, whereas areas to the west of the mountains will experience generally lighter movements. In quiet areas where winds are light, birders should listen flight calls as calling events should be widespread in many areas of the region. By the end of the forecast period, high pressure builds in coastal and offshore areas, bringing southerly winds and greatly diminished movements to the entire region."
