"Alignment" means that a bird tends to turn so that it is moving in the same direction that nearby birds are moving. The birds follow three rules: "alignment", "separation", and "cohesion". Rather, each bird is following exactly the same set of rules, from which flocks emerge. (The resulting motion also resembles schools of fish.) The flocks that appear in this model are not created or led in any way by special leader birds. This model is an attempt to mimic the flocking of birds.

The rural crime team manager said on Twitter despite “widespread publicity and theories”, some of the murmuration had not being able to pull back and died on impact. North Wales Police’s Rob Taylor said they had gone into a dive murmuration together and hit the tarmac. While this phenomenon is usually a graceful and beautiful endeavor, it’s possible that a portion of a flock of birds in Mexico, similar to the flock of birds in Wales, made a miscalculation when evading a predator and ended up crashing into the ground. Birds occasionally fly in a murmuration, a fluid formation involving hundreds or thousands of birds. While the startling sight of so many dead starlings spurred some wild speculation, local authorities concluded that the birds crashed while trying to evade a predator. In 2017, on a road in North Wales, 225 starlings were found dead. It’s possible, too, that this crash was the result of simple bird-error. However, a zootechnical veterinarian on the scene hypothesized that the birds may have been impacted by local pollution, cold temperatures, or nearby powerlines. The exact cause for this surreal scene isn’t known at this time. Neighbors of the sector explained that it was around 5 in the morning when the birds began to collapse, so later they called the police to come to the scene. Upon arrival, the police officers observed a hundred dead birds of the Yellow-headed Thrush (Xanthocephalus) species, which migrate from northern Canada to northern Mexico where they spend the winter. On the morning of this Monday, February 07, a peculiar finding was recorded in the streets of the Álvaro Obregón sectional, when inhabitants of said community observed hundreds of birds commonly known in this region as “blackbirds” dead in streets and sidewalks.
