Spring Waterbird Count 5/13-5/19

We have reached the heart of May, bringing warmer temperatures and even more new birds! May 13 started slow though as steady winds out of the northwest essentially halted most bird movement. However, I was still treated to the striking white wings of both of our white-winged gulls! A very clean looking adult Iceland [...]

Spring Raptor Count Blog 5/12-18–Caracara Round 2!

It has been a busy week at Whitefish Point! Mid May is a very exciting time of year, as raptor flights can boil up into large kettles, passerine flights are large and diverse, and the chance for rare birds increases. We'll start with the raptors. "Peregrine Week" lived up to its name, with 19 [...]

Spring Waterbird Count 5/6-5/12

This observation period continued to bring new arrivals both over the water and back over land, as well as some exciting counts. This post kicks off on the overcast morning of May 6, where upon arriving at the station, I was greeted by a first-cycle Glaucous Gull amongst a few other gulls sitting along [...]

Spring Raptor Count Blog 5/5-5/11–Marching Onward

There have been no Caracara sightings since last week, making for a much less exciting blog post this week. Spring marches ever on, but with a slightly different tone than before. Now, warbler song has begun to pepper in between bursts of Sharp-shinned Hawks, and Blue Jay flocks provide a dazzling backdrop against sunny [...]

Spring Waterbird Count 4/29-5/05

April turned into May during this observation period, with the birds continuing to tell the tale of seasons changing, despite the weather not. April 29 is the first day this post will cover, another day dominated by westerly winds. Moderate numbers of waterfowl were detected, and this was the first day of noticeable loon [...]

Spring Raptor Count Blog 4/28-5/4–CARACARA!

April has come and gone, and May is here! While temps have barely reached a sweltering 50F, a few small patches of snow remain tucked in the shadows of the dunes. Overhead, migration rolls right along! The last few days of April only held a couple of meager Sharp-shinned Hawk and Broad-winged Hawk flights. [...]

Spring Waterbird Count 4/22-4/28

As we rounded the second official week of the spring waterbird count, the signs of spring continue to show themselves. This is indicated by the disappearance of much of the ice along the shoreline and the influx of waterbirds taking advantage of these open waters. This was noticeable on April 22 when a Long-tailed [...]

Spring Raptor Count 4/21-27–Migration is Peaking

This week has been the most exciting of the season thus far! One of the greatest tests of spring hawkwatching is the long wait for the explosion of raptor flight in late April. This year did not disappoint! We started the week off strong with a beautiful sunny day with light winds, which created [...]

Welcome back as we kick off another year at the spring waterbird count!

Spring Raptor Count 4/14-20–Hawks to Count

Late April is always an exciting time at the Hawk Count, for this is the time that raptor diversity increases to the maximum and flights really build some steam. This week lived up to the call! We started off with a bang on the 14th with the first triple-digit Sharp-shinned Hawk flight of the [...]
