Climate Change…

…Affecting Bird Migration.

Anyone even remotely interested in birds is aware of the issue involving bird collisions with buildings in large cities… especially cities situated on large bodies of water such as Toronto and Chicago. 

The feathered collision victims are gathered by volunteers and kept in freezers until they are transferred to – in the case of Toronto – the Royal Ontario Museum, and Chicago – the Chicago Field Museum.

Using information collected by volunteers that gather these birds, researchers are able to piece together timing of migration by specific species and have determined that flocks of migrating birds are passing through Chicago about a week earlier than they used to.

    Do Sandhill Cranes depart earlier or later in the fall depending upon the weather around them? When there is an earlier Winter, do the birds depart early? Did the cranes depart earlier this Winter (a cold one) compared to last year (a warm one)?

    Wouldn’t the earlier departure of birds to their winter feeding grounds be considered an indication of global cooling rather than global warming? If the northern parts of the globe were really getting hotter, then it would seem logical that birds should leave later rather than earlier to their winter feeding grounds?
