They will either roost on the bank or the water. At Sunset they sense that intensity of light is falling and they are usually fly higher at higher at some hight they see lights brighter towards west.
Many birds are more social in winter and will roost together in larger numbers.Some birds may only have to travel a short distance from where they feed during the day to where they spend the night but others will travel many miles. We see them heading west in the evening to roost in a large wooded area by the highway and it's sooo noisy. Garden birds may feed on the feeders and then roost in the hedges around it.
My 4 year old tells me that they are going to the mall to do their holiday shopping. We have evidence that suggests that starlings could indeed be safer from predation in larger and denser flocks, through the confusion of predatorsBenedict Hogan, PhD student at University of BristolBenedict Hogan, a PhD student from the University of Bristol said: “What we aimed to do was to find out whether or not confusion does occur in these massive and complex aggregations, like those of starlings.“We found that, in line with the predictions of the confusion effect, participants had more difficulty in capturing a target starling in larger flocks, and in denser flocks; and that these effects interacted.“This means we have evidence that suggests that starlings could indeed be safer from predation in larger and denser flocks, through the confusion of predators.“However, it is likely that predator confusion is only one of many functions of these impressive groups in starlings.“Computerised experiments like this may allow us to test other potential functions in starling groups, and similar simulations may help others to understand the mechanisms and functions of complex groups in other species.” See today's front and back pages, download the newspaper,
We see them heading west in the evening to roost in a large wooded area by the highway and it's sooo noisy. As well as birds, I am particularly interested in invertebrates, reptiles and amphibians.These birds should all be heading back to their shared roost site. Crows don't see well at night; owls do. Every morning around 6:45am, my son and I see a murder of crows head west for the day. Where do the hundreds of crows flying west over SE Portland go every evening at sunset?

By telling vivid, sound-rich stories about birds and the challenges they face, BirdNote inspires listeners to care about the natural world – and take steps to protect it.Crows gather by the thousands to spend the night together The confusion effect is often discussed when considering the causes of large and complex groups like those of starlings and shoals of fish, but there is little empirical evidence that these groups induce predator confusionIn fact, most evidence for confusion comes from experiments with very small groups, less than ten birds.The study was published in the journal Royal Society Open Science. 1 decade ago. Lv 6. Many thousands of starlings can fly together in a flock, also known as a murmeration.
Many thousands of starlings can fly together in a flock, also known as a murmeration.Their spectacular swirling displays are captivating to the eye, but very little is known about why the birds move in this way.Researchers observed that flocks of starlings are larger, and more densely packed in areas with predators such as hawks.They also found out attacks by predators are more likely to fail, when directed against larger groups of starlings.This suggested the birds fly in these large groups to protect themselves from predators.These large groups can protect birds in a number of ways.
