In the time before spring, migratory birds begin to grow restless on their "wintering grounds". They begin to eat more, in an attempt to add body fat that will be needed on migration. As the days grow longer, the restlessness increases, until eventually the birds take flight. Even when migratory songbirds are caged, they will still show this behaviour, fluttering towards the side of the cage in the direction they would be migrating in the wild. This phenomenon, termed zugunruhe by the german scientists who conducted studies involving small migratory songbirds in captivity.
I believe this urge also exists in birders, although it isn't very well documented and to my knowledge lacks a name (lets call it migration anticipation). Unlike in birds, the birders aren't compelled to migrate, instead they want the experience, the immersion in migration. It lies dormant through December and January in the birders of Ontario, then, in mid February things begin to stir. Horned Larks begin to show up on roadsides and American Crows stream northward into Ontario. During the first warm days in the later part of February, when the cardinals start singing and the snow starts melting, somethings flips in the birder's brains. They are drawn outdoors, where they begin searching for signs of migration. For the more obsessed birders, the draw may be strong enough for them to walk/drive to local patches of open water and marshes in search of the first blackbirds and ducks of the year. Most of the time there is nothing there, as it is still February and migration is weeks away. The birders begin to dream of migration, their thoughts full of Killdeer, woodcocks and meadowlarks. Then a cold snap hits, jerking them back to the harsh reality that it is indeed still winter. In the days and weeks to follow they will grow impatient, yearning for the first warm blast of air from the south, the first robins, the first blackbirds. Some years, when the cold weather persists into late March or even April, the birders grow increasing impatient. For some of those who live away from the southern Great Lakes, the urge to see birds will make them take a trip down to the Long Point or Pelee area, in serch of early migants to fulfill their cravings.
The last few days have been gorgeous on the Peninsula, warm(ish) and sunny. This has awakened something in me, this growing "migration anticipation". I decided to try the first skywatch of the year in my yard on Friday (19th). The sun was out and it was relatively warm (-2°C) so I wanted to see if there were any signs of migration around. At first it was quiet, and then a Bald Eagle passed overhead heading north, followed by another in 10 minutes. In the 2 hours I spent out in my yard I saw a total of 6 Bald Eagles, all adults heading north. Also present were American Crows, thought it was hard to tell if they were true migrants (wishful thinking) or simply local birds.
- The next day (the 20th), I tried another impromptu skywatch in the yard. It was quieter than the previous day, with 3 Bald Eagles and a lone Red-tailed Hawk. Just as I was about to head inside I looked up and spotted an adult Golden Eagle soaring over... saweet! I sometimes see adult Goldens here in late February, they are among the earliest of the migrant raptors here and are always a highlight see. In the evening, calling Great Horned and Barred Owls were nice to hear.
- Today it was overcast all morning, with a damp wind out of the south. I counted 3 Bald Eagles over the yard, 2 together in late morning then a lone bird in the afternoon. Still fun to see. Later in the day two White-winged Crossbills flew over ~ my first of the year.
That's it for now folks! They're coming... just another few weeks
