3 days ago · Migrating birds regularly fly up to 10,000 feet above ground, although seasonal timing and weather conditions dramatically impact their distributions. Note: Direction, speed, and altitude may be unreliable when the number of birds in flight is low. In such cases, chart data may include gaps.
Dec 23, 2018 · However, the range of this effect is <200 ft, so a weather radar can't be relied on to prevent bird strikes. It's also not well-studied and not verified across a wide range of species. The beam might also completely miss the birds due to scanning.
BirdCast applies weather surveillance radar to gather information on the numbers, flight directions, speeds and altitudes of birds aloft in order to expand the understanding of migratory bird movement. In this article, we’ll give you a brief overview and a behind-the-scenes look at the ways we apply radar data to study bird migration.

Of all the problems faced by bluebird landlords, house sparrows are easily the worst. House Sparrows (HOSP's) are an overly aggressive, alien species of bird that prefers similar habitats and nesting locations as bluebirds. The male sparrow is particularly nasty and will often kill not just the young bluebirds but even the adults and eggs too. Hous...
1. Blowflies - blowfly infestations can occur in any nestbox and is somewhat unpredictable. It's really the blowfly larvae that are the problem. The adults lay the eggs in the nest, which then hatch into larvae which feed off the blood of young birds. They reside underneath the nest during the day, and then crawl upward to attach themselves to the ...
1. Mice- mice can sometimes infest nest boxes left out in the winter. If mice have nested in a box, you need to remove the nest carefully. Deer mice and some other species are known to carry a disease called hantavirus. Hantavirus can be fatal to humans, so it is VERY important to take precautions when getting mice out of box. Always wear rubber gl...
NOTE:You MUST monitor your nest boxes in order to become aware of whether your boxes are vulnerable to predators. Below is a summary of the major types of predators that can attack nesting boxes to go after adults, young, or eggs. 1. Hawks- Cooper's Hawks, and Sharp-Shinned hawks are two common predators of smaller birds. Coopers are especially com...
Long cool stretches of wet weather are one of the major causes of nest failures. When these weather conditions persist for too long, bluebirds have difficulty finding food. This will eventually weaken the adults and prevent them from having the energy to feed hatched young. The result is that the bluebirds will stop feeding the young in order to sa...
Sep 27, 2019 · Cold fronts also tend to have northerly winds (which blow north to south), which aid our feathered friends in their southward migration. Check your weather radar regularly this season, or check out BirdCast: a special forecast that predicts which birds will be moving near you! Here’s what to expect over the next few months in Michigan:

Feb 24, 2023 · Thousands of birds can be detected by radar in features that are known as roost rings. The National Weather Service said these often appear as the birds take flight around dawn to hunt insects. In Ohio and other states around the Great Lakes, these radar depictions are common in the summer and fall before annual migrations begin.
