This year's annual Waukegan Christmas Bird Count could be good for both rare sightings at backyard feeders and even more numerous common birds because of the snow cover conditions, according to the organizer.

"So the possibility exists for a good number of birds going to feeders and those counts are important for the census for a more accurate count of the birds that use this area," said Greenberg.

If you see two female red cardinals in the morning and then two females at noon, don't count four, just two, because they are probably the same birds. If you see a male later, then you would add it.

"Birds are affected by the weather conditions, and with the snow, ice birds are found to resort to feeders when certain food sources they normally would tap are covered," said Joel Greenberg, organizer of the annual event.

"This year might also have some rare birds show up at feeders," he said, like the thistle loving Eurasian Brambling or Red Pole or pine siskin, smaller finch like birds.

In the past, the Waukegan Christmas Bird Count has ranked in the top ten nationally and in Canada for the number of people participating in the feeder count.

Greenberg has been running the count for decades and will be out all day checking various areas for birds with three other team members. At the end of the day, the groups gather to reveal what birds they spotted over a potluck dinner.
