Brothertown Cattle Egrets

Last Wednesday while staying on the west side of Lake Winnebago, Derek and I decided  to take the half hour trip around the lower part of the lake to look for Cattle Egrets. Cattle Egrets technically are not considered rare for this part of the state but they can be tough to find some years.Fortunately, our girlfriends also agreed to join us in our search.

We turned onto lake shore drive where most of the sightings occur and almost immediately spotted a single Cattle Egret in a grassy field to the north of the road. It seemed to be content to sit by the small creek running through grass. We spent some time watching it and listening to a calling Eastern Wood-Peewee before moving on to see if we could find more.

We continued down the road in the direction of some large groups of cows hoping we could find egrets following close behind. We struck out on more egrets but we did find a field with about 200 Ring-billed Gulls and a weird looking hawk that was most likely a juvenile Red-tailed.

We were about to turn around and head back when my girlfriend Bri (aka the worlds greatest egret spotter) noticed some small white shapes in the distance way off to the south east. We immediately got excited when we noticed a crass street that could take us right next to where this group of egrets were. We became even more excited when we saw 12 of them all at close range associating with the cattle.

We had a great time watching them lurk around the cattle and pick insects and other items up from the weeds. Occasionally they would take flight and relocate further down the field, but they would always return to the cows.

It’s always hard to rip yourself away from cool birds but we wanted to give them some space so we took off back to the house on the west side of the lake feeling great about our close up sighting.

Birds Of Lake Winnebago

We took a family trip out to the western shores of Lake Winnebago in Fond Du Lac County. Of course, we were keeping an eye out for birds.

When we went out in the back yard of house we were staying at we immediately started seeing birds. In the trees near the water there House Finches and a single Warbling Vireo. Foraging along the ground were House Sparrows, Chipping Sparrows, Mourning Doves, and American Robins. For a few minutes a Spotted Sandpiper also made a brief appearance on the lawn.

Out over the water there were plenty of Ring-billed Gulls and Double-crested Cormorants. Every so often the majestic American White Pelicans flew over or sometimes even landed within 50 feet of the shore. The raspy call of the Forster’s Tern could also be heard from time to time as groups of them flew past.

Some of the most interesting birds to watch were the many swallows swirling around our dock. To the south, Purple Martins could be heard and sometimes seen. From the north, Northern Roughed-winged Swallows flew threw, and just one dock away a colony of Barn Swallows gathered and dispersed every fifteen minutes or so. At the end of the day we were mesmerized by the swallows swooping just inches away from the water’s surface with the sunset colors in the background.

It was a decent birding day given the fact that we weren’t specifically trying to bird. We’ll see if we can find anything else interesting the rest of the week. Stay tuned.

Manitowoc And Sheboygan Lakefront

Yesterday Derek and I met Rob in Manitowoc to see if we could find any interesting birds out on the lake. We started out checking the impoundment where there was a surprising lack of gull diversity. The only species present were Ring-Billed Gulls. Walking out to the impoundment we saw many Mallards and two Hooded Mergansers. Upon arriving at the walkway that circles the small lagoon we looked out over the shoreline with the sun in our eyes. There were two Tern species: Caspian and Forster’s, a Great Blue Heron, and several American White Pelicans. On the far shore we were able to see some peeps. Two were Semipalmated Sandpipers and one was a Least.

We walked around the the lagoon hopping from rock to rock to try and get a view of the birds sitting on the sand bar. Along the way we encountered high numbers of Song Sparrows. Most of the time they could be heard but not seen. We also located a few Spotted Sandpipers that would fly in front of us in order to stay a comfortable distance away.

Spotted Sandpipers

By the time we got to the east side of the impoundment many of the gulls had departed from the lagoon, as a result we continued on toward the many gulls that were sitting on the break wall. On the way there, a crowd of Barn Swallows lifted off from the grasses. The birds swirled around us and some landed on the taller, stronger stalks. Almost simultaneously someone with a dog spooked all of the gulls. Feeling a bit dejected we continued around and located two silhouetted Short-Billed Dowitchers.


Notable misses in Manitowoc were Bonaparte’s Gulls, Franklin’s Gulls, and Little Gulls that usually summer there.

Next we headed to Sheboygan where we were primarily going to check the north point. There were many birds sitting on the rock shelf just off-shore. Many of these birds were Herring and Ring-Billed Gulls but we did see some Bonaparte’s Gulls and what appeared to be a pair of first cycle Lesser Black-Backed Gulls. Two Spotted Sandpipers flew from rock to rock on the shore and on the rock island. We also noticed Double-Crested Cormorants, Caspian Terns, Forster’s Terns, and Common Terns. We once again missed out on Franklin’s Gulls at this location.

Bonaparte’s Gulls

In all, we didn’t have a great day at the lake as we didn’t come up with any difficult to find birds but it was still great to be outside and get the chance to look!

Retzer In July

Today I went to Retzer Nature Center in Waukesha County to see how things have changed with July winding down. I started by taking the northeastern trail that leads to the pond. The usual birds were in this area including American Goldfinches and Common Yellowthroats. I was able to get a good look at a Common Yellowthroat singing in a tree but the mosquitoes and deer flies were so bad I didn’t stay still long enough to get an in-focus picture. This was a theme today. The bugs were easily the wort I’ve ever encountered at Retzer. The precipitation we’ve had combined with the lac of wind was the perfect storm for them today and they followed me all the way through the forested part of the Nature Center.

I moved through the forest trail quickly hoping to lose the bugs following me when I got into the open prairie. While I was in the woods I heard a few Indigo Buntings and saw numerous American Robins. I also startled a deer munching on plants.

When I got to the prairie trail I was unable to hear many of the calls that were so prolific just a month ago. There were not any Dickcissel or Bobolink, and only one Henslow’s Sparrow. There were however still many Field Sparrows and Clay-Colored Sparrows.


On the north side of the hill all of the tall grass was cut eliminating habitat for the Henslow’s and Savannah Sparrows. However, in the tree line farther north and tall grasses to the east there were still large numbers of birds. Most of these were juvenile Indigo Buntings and Field Sparrows but there were also several Eastern Kingbirds, Ruby-Throated Hummingbirds, more Common Yellowthroats, and an Eastern Towhee.

Female Common Yelowthroat

On the way out of the Nature Center I got looks at a Gray Catbird and a Red-Eyed Vireo that was too crafty for me to get a photo of. The insects followed me the whole time until I got to the car.

Ruby-Throated Hummingbird

I would have liked more time to search through the birds on the north side of the Nature Center but the bugs proved to be too much to deal with for me. Next time I’ll make sure there’s more of a breeze before I go.

Quest for the Grenada Dove – Part 2!

Earlier this year I went to the tropical island of Grenada to search for one of the worlds rarest dove species: the Grenada Dove.

As I look through the videos from birding in Grenada and find out more information about the local species, the thing that strikes me the most is that there is still so much to learn about them. Being so rare and on a relatively small island, few have studied the habits of this bird. While very little is known about the Grenada Dove, here are some things that we do know.

  1. Grenada Doves are endemic to the island of Grenada (Meaning they are only native to the island)
  2. The Dove is classified as Critically Endangered (IUCN Red List) with about 130 individuals left  (87 mature individuals) according to the Cornell Lab of Ornithology.
  3. The Grenada Dove is the national bird of Grenada
  4. The introduction of the Indian Mongoose had a negative impact on the Dove’s population
  5. The Mt. Hartman National Park was established by the Government of Grenada in 1996  to help protect the Dove’s habitat
  6. When spooked, the Dove is more apt to walk on the ground through the brush than fly away
  7. The population may be isolated to small areas where their habitat is still present

To learn more about the Dove, stay tuned for the video, coming soon titled “Quest for the Grenada Dove.”

Birds Of Watonwan County, Minnesota

This weekend I traveled to Watonwan County in Minnesota for a wedding. Based on the ebird statistics, Watonwan doesn’t appear to be birded very frequently with the exception of a few individuals. Due to wedding festivities my birding efforts were mostly incidental, but I was still able to get over 20 species in the short time I had.


We stayed on a farm surrounded on all sides by corn fields. Driving down the long gravel driveway the first birds I noticed were the many Killdeer scurrying along the sides of the roads as we passed. Also on the roads were the occasional Horned Lark. Driving past the cornfields there wasn’t much in terms of avian life with the exception of the occasional Red-Winged Blackbird popping up from the low corn stalks or Barn Swallow flying overhead. The farm house was in a grove of trees creating a small forest island otherwise completely surrounded by fields. This small oasis was where the majority of the birds could be found. Black-Capped Chickadees, American Goldfinches, Downy Woodpeckers, Common Grackles, ad White-Breasted Nuthatches were routine feeder visitors and Rose-Breasted Grosbeaks and Baltimore Orioles were present but made fewer appearances.

The noisiest birds on the property were the House Wrens. They chattered from all sides of the house and occasionally perched out in the open, never for very long though. Some other loud species in the surrounding woods were the Great-Crested Flycatchers and Eastern Wood-Pewees. I could hear at least two of each species.

Great-Crested Flycatcher

We drove a few miles down the county roads through the corn fields in order to get to some tennis courts in the small town of St. James. On the way, we stopped by a field where long grasses were growing and a small creek intersected the gravel road. This section of the road seemed to be the epicenter of bird activity as many Red-Winged Blackbirds were flying around the field and landing on the corn stalks that lined the edge of the field. A Belted Kingfisher suddenly perched up on a wire near the creek and an Eastern Kingbird landed in the middle of the road and caught an insect. At least two Dickcissel could be heard calling in the field. One of them ended up perching in a nearby deciduous plant.

House Wren

We continued to the St. James tennis courts after watching the field for about ten minutes. Even when playing tennis I’m always keeping an eye on the birds. There were House Sparrows, Mourning Doves, and American Robins in the trees and other structures around the courts. Overhead there were six Chimney Swifts clicking and chattering.

In my limited time birding I came up with 26 species. None of them would be considered rare, but it was still a nice experience finding birds in the open fields of southern Minnesota.

Blue Grosbeak vs. Indigo Bunting

With summer upon us, some of the brightest colored birds in North America are nesting all across the country including the Midwest. Two of these birds that can be somewhat difficult to tell apart without knowing the field markings are the Blue Grosbeak and the Indigo Bunting. Both of these species are bright blue, frequently overlap in geographic range, and can be found around the same habitat. This means birders are likely to encounter both at some point. The good news is that there are some surefire ways to differentiate the two.

As far as size is concerned. There is a discernible difference between a Blue Grosbeak and an Indigo Bunting. Blue Grosbeaks typically range between 15 and 16 cm while Indigo Buntings are between 12 and 13 cm. This means that in theory, an Indigo Bunting should never be as large as even a relatively small Blue Grosbeak. While it is hard to tell size on a single bird by itself, a side by side comparison shows this difference distinctly.

The range of these two species differs slightly with much of it overlapping.

Blue Grosbeaks general range is as far south as Central America during the winter months and as far north as North Dakota in summer. They span from the west coast to the east coast and can be found readily in the southern states. While the Blue Grosbeak is widespread in the United States, their basic range does not typically go north of Colorado and Indiana with only a few individuals spotted annually during summer in states like Wisconsin. They do however appear farther north in the central part of the United States as they also summer in Oklahoma and the Dakotas.

Blue Grosbeak Range

Much like the Blue Grosbeak, Indigo Buntings winter as far south as Central America. This bright blue bird also inhabits most of the southern United States with the exception of parts of Arizona and Texas. It is also notable to note that the Indigo Buntings range seems to skip over western Mexico. Unlike Blue Grosbeaks, Indigo Buntings make their way much farther north in summer as they are found in every state east of Montana and even southern parts of Canada.

Indigo Bunting Range


Bill size is a solid way to differentiate between these two species. The indigo Bunting has a relatively small, conical bill while the Blue Grosbeak has a comparatively larger bill. In addition, The Indigo Bunting has a completely one colored gray/silver bill. The Blue Grosbeak often sports a two colored bill with a darker gray on the upper mandible and lighter gray on the bottom mandible.

Field Markings

Though both of these birds are a very similar shade of blue, there are some differences in pattern and coloration that go a long way in identification.

The Blue Grosbeak has a small black mask near the base of the bill going over the eye that the Indigo Bunting lacks. They also have very distinctive rusty wing bars that serve as an extremely reliable field marking. Female Blue Grosbeaks lack the deep blue of the males (instead they are a dark tan/light brown color) but still have the same rust colored wing bars.

Indigo Buntings are almost entirely blue with some of their only other coloring being a varied gray to black on their wings. They do have a very small amount of black near the base of the bill but not nearly to the degree that the Blue Grosbeak does. Females are a lighter shade of tan than the Blue Grosbeak and lack the wing bars of the Blue Grosbeak females.

These two species often co-exist in the same habitat and overlap readily in the United States and Mexico. Even in ranges where only one of these species would be expected. It is good to know the ways to tell them apart just in case.
