Autumn's birds delay migration

Every year, ducks and geese spend their summers and late fall in the northern region of Europe. Bird watchers have been keeping track of the migratory patterns. The birds have been delayed up to a month compare to the past 30 years of research. Even more shockingly,  there has been a huge decrease in the number of birds that do pass over the migration tracking point. For example, the white fronted geese population has dropped by 75%. In the past, around 30 years go, it would be normal for the populations of birds to be 6000. But now a days, there is a shocking 500 birds. This is a drastic decrease in  populations. So now for the future, a team in Finland will be conducting more research to see if populations are declining in the species or if the migratory patterns have change to go more north due to warming weathers else where.
