Bob Kelleher from MPR did a story on the migration and the possibility of wind turbines on the N. Shore. The day we chose was foggy and rainy. Needless to say, there were only a handful of birds but Bob did a nice job piecing together a story anyway. Here's the link:

"1000s of dead birds in Lake Superior"
I just found out that beginning on Sept 2nd, fishermen on Lake Superior were reporting "wind rows" of 1000s of dead birds floating in the Lake. The birds were described as being from warbler-size to woodpeckers to gulls. We had a storm come through the evening of Sept 1st that continued through the 2nd with high north winds and heavy rain.
I don't know the magnitude of this event nor do I know why the birds didn't make it. I can speculate exhaustion, inability to find or get to shore, or possibly a downdraft. I'm attempting contact with the fishermen to see if I can get any other information and piece together what may have happened and the possible magnitude of this mortality event. An interesting note is that the morning of Sept 1st, we recorded over 6000 birds flying inland from Lake Superior from a one-mile radius observation area. Assuming ~6000 birds were flying inland at every one-mile radius spot along the North Shore, I would guess that millions of birds were actively migrating during this time and quite possibly during the storm.
Lets hope the magnitude of this mortality event is not newsworthy. I'll post what I find out.

Small birds still moving ... my the thousands
We have begun our second round of surveys moving up the North Shore and still the morning flights are amazing. The birds in the forests have shifted from long distance migrants (warblers, vireos...) to the short-distance migrants (creepers, wrens, sparrows). I'm going to guess those unidentified birds in the mornings coming in off of Lake Superior have probably down the same shift. Although, Swainson's thrushes have still been observed.
Tomorrow (9/19) on of the crew will be at the Lax Lake overlook near Silver Bay. We also hope to survey from Pincushion Mountain in Grand Marais on Monday the 20th depending on weather.

Pincushion Mountain
After some windy cold days between Duluth and Finland, the migration crew is heading up the shore to Grand Marais. One of the best places to watch the migration is from Pincushion Mountain accessed from the ski trails up the Gunflint Trail from Grand Marais. To join us, park in the Pincushion lot and hike beyond the Pincushion loop to the tip of the ridge. If you are unable to hike out to the tip of Pincushion Mountain, the parklot also offers a good view of birds on a west wind day as they travel down the shoreline. We will be at Pincushion sometime towards the weekend. If you want to join us, email me your contact info and I will let you know the exact day we will be surveying there (apeterson@hawkridge.org).

WOW
The crew was surveying near Castle Danger, MN this morning and counted 6000+ passerines (mostly warblers) from 6:30am-7:30am flying inland from Lake Superior. This passerine flight continued for about 2.5 hours after sunrise then almost abruptly stopped. The total number of birds was very impressive as well as the number of Rose-breasted Grosbeaks among the warblers. Also, the birds were not in flocks but spread out across the entire sky and flying west. Their flight calls were as one of my crew members put it, "like a chorus of bells" (although none really sound like bells). The raptor flight was fairly light with a few small falcons, sharp-shinneds, and broad-wingeds passing by while the vultures cruised up and down the shore.
We plan to be at the Lax Lake Overlook in Tettegouch S.P. on Friday or Saturday. If you want to see the spectacular numbers, be there at sunrise.

The migration is well underway....
We held our "training" for migration surveys this morning in Duluth and were overwhelmed by thousands of passerines moving down the shore. A record 10,000+ Cedar Waxwings were accompanied by Grackles, Blackbirds, Swallows, Blue Jays, Robins, Kingbirds, and Warblers. It was a great start to the season and we begin our shoreline surveys tomorrow (8/30/10). One of our researchers will be counting at the Knife River Wayside just up the shore from Duluth. On Tuesday (8/31/10) a researcher will be counting from Wolf Rock on the Superior Hiking Trail access in Castle Danger (NE of Two Harbors).
Check back for count updates and observer locations.

Migration Countdown
The North Shore bird migration will soon be underway. We are gearing up to begin surveys in September. If you are planning to visit the North Shore this fall and want to experience the North Shore bird migration, please join us during our surveys! Here is a list of the best survey sites to visit (nearest town, actual location):
1.Duluth, Knife River Wayside
2.Two Harbors, Wolf Rock on the Superior Hiking Trail
3.Silver Bay, Lax Lake Overlook Tettegouche State Park
4.Tofte, Tofte Peak Temperance State Park
5.Grand Marais, Pincushion Mountain on the Superior Hiking Trail and Pincushion ski trails
We rotate through our survey locations so if you want to join us, please check back for a schedule or email me with your contact information and location of interest. All locations are public so even if we are not present, you will be able to see the migration from these areas on your own. My suggestion is to arrive at sunrise to catch both the morning passerine flight as well as the midmorning raptor flight.
See you soon!
