Migration Counts

Seasonal staff at WPBO conduct waterbird counts in the spring and fall and a spring raptor count. During the seasons, counts are conducted daily. Raptor counts run March 15-May 31 from 9 a.m. to 5 p.m. Waterbird counts run April 15-May 31 and August 15-November 15, 8 hours starting at dawn daily during each season. The Hawk Deck and Waterbird Shack are accessible to the public, and you can follow this blog to get regular updates during the counting seasons!

Waterbird Count Update: May 25-31

The last week of the 2023 spring waterbird count has been defined by two things: the mosquito hatch and the Canada Goose molt flight. In their own right, both of these happenings are fairly remarkable natural phenomena.  We've got two periods of heavy Canada Goose movement at Whitefish Point. The first is towards the [...]

Notes from the Hawk Deck: Week Eight (5/23-5/29)

The final days of the spring raptor count brought a mix of interesting rarities and large holiday crowds to the hawk deck. The week began with a smaller BROAD-WINGED HAWK flight on May 23, with just a double-digit day count; however, this was enough to tilt the species season total over the 8,000-mark. This spring continues [...]

Spring Waterbird Count Update: May 18-24

Late May is just a time of year that feels good. It’s sunny; it’s warm. Black flies and mosquitoes have emerged down in Paradise, but the Point is bite-free for a couple of days or so. It’s one of the few genuinely comfortable times we get at a place that, of all this continent’s bird observatories, [...]

Notes from the Hawk Deck: Week Seven (5/16 – 5/22)

The momentum of raptor migration along the Point has waned dramatically as we enter the second half of May. The week began with a second consecutive day of a BLACK VULTURE documented from the hawk deck. This was likely the same bird observed in the late afternoon on May 15, as the silvery-winged vulture [...]

Notes from the Hawk Deck: Week Six (5/8- 5/15)

The week began with two great BROAD-WINGED HAWK flights on May 8 and 9, with 1,840 and 2,400 migrants, respectively, being documented throughout both days. This was the largest push of broad-wings so far this season and will likely be the peak as numbers have begun to taper off. The season total sits at [...]

Waterbird Count Update: May 4-10 2023

When I get my first triple-digit Bonaparte’s Gull flight of the spring, that’s a harbinger: time to start going out for night flight. Today, May 10, 499 Bonys, delicate and ternlike, traveled north during the day’s count. I kept my word, loaded up around 8:30 p.m., walked down the beach towards the tip as [...]

Notes from the Hawk Deck: Week Five (5/2 – 5/7)

The month of May began with soggy, wet conditions, and the days that followed (May 2 and 3) did not fare much better. Northwest winds funneled in off the lake, keeping much of the raptor movement at bay. Conditions improved dramatically by May 4, and BROAD-WINGED HAWK kettles began forming by the late morning hours. Similar [...]

Shack Talk: WPBO Waterbird Count, April 27–May 3

Shack Talk: Sunrise It would be a stretch to say Leonard and I shared the sunrise on May 2, for the last week and a half has been mostly gray skies. I’ve risen — and the sun, I suppose, has too — but we haven’t really seen it. But, sunrise or not, Leonard was [...]

Notes from the Hawk Deck: Week Four (4/25-5/1)

As the saying goes: April showers bring May raptors. This past April brought its fair share of precipitation (in the form of rain and snow) and opposing northwest headwinds. In spite of less favorable conditions during certain blocks of the month, the raptor count was able to complete the month with an above-average monthly total [...]

Getting Somewhere: 2023 WPBO Spring Waterbird Count Update Week 2, April 20-26.

It's been a fairly quiet week at the waterbird count, with conditions ranging from not-that-bad (light northerlies, dry skies, and little flocks of Common Mergansers) to pretty terrible (snow squalls, strong northerlies, zero visibility, zero avian movement). So it goes during spring on Superior. We've had our first White-winged Scoters (showing first on April [...]
