The Spring Brock Report

It’s been a few weeks now, so it’s probably time for a little update.  All of the lakefront reports for the dunes area from March-May, 2014 are now all available to view.  The Brock Report has been affectionately titled “where Brendan Grube birded at this spring” for this issue.

To access it, visit the NIMBA site and click on the pdf to bring it up.

Good birds are still to be found in June and early July.  Recent goodies have included the rare breeding pair of King Rails and the Grant St. Wetlands, and last week’s super goodie Yellow-crowned Night-Heron that spent nearly a week in a backyard near Westville.  The latter had gone ten years without a sighting in the dunes area.  Get out and bird!

3 Seasons of Counting

Waterfowl watching the first week of the longshore flight in 2014.

Waterfowl watching the first week of the longshore flight in 2014.

It’s hard to believe three short months ago we were standing atop an near arctic shoreline shivering as we waited for ice to break up and Snowy Owls to drift past the lake.  The past three years have seen average springs, warm springs, and now cold springs.  In just three years, it’s clear that the average spring is better for counting migrating birds.  Now, in no way can we take into account irruptions of certain species, seasonal movements that vary each year.  All these can affect individual species counts, but as a whole, the extreme cold and hot weather patterns couldn’t beat the average high for bird flights.

The last official count of the season took place yesterday, June 1.  A few late migrants will trickle through the first days of June, but by June 5 most are done migrating, breeding is in high gear, and the first hints of fall migration are only a few weeks ago.  Proof that the migration has come to and end, Sunday’s count was a measly 125 birds.  It was the lowest longshore count of the season.  The second lowest…. the first day of our season, March 9. So how did the year’s compare:

2012: 285,383 birds
2013: 428,374 birds
2014: 260,884 birds

It will take some time to analyze all the data.  But one species still stands out.  American Robins, one of the most abundant migrants over the dunes, especially mid-March through mid-April, posted dismal totals this year.  Compare this year’s 8,152, with last year’s 35,000 and the 37,000 seen in 2012.  Where were all the robins.  Strangely, you’d expect the colder and snowier winter to drive more robins south, which would mean that more robins would have streamed north.  One theory was has it that the productive summer resulted in a good winter crop of berries throughout the northern US.  Just as no winter finches irrupted this winter, few robins did either.  Thus, you might consider robins an  irruptive species.

The last migrants seen on June 1 consisted of typical late migrants.  Brendan logged both Olive-sided and Yellow-bellied Flycatchers, Purple Martin, Cedar Waxwings, Wilson’s and Canada Warblers, and a late and odd Lark Sparrow still visiting the site.

Expect us to better compare the last three years and give some insight into the migration over the dunes in the coming weeks.  We’ll also continue to give birders a peak into the breeding season birds in the coming months and send you to the great dune sites to see them.  Until then, we’ll leave you with one final video of some of the late and amazing birds seen in the dunes (and general NW Indiana area) this past week.

Down to 14

As fast as spring migration enters, it quietly fades away.  Without hurrah, the spring sounds exit, with the summer breeders still going strong as June comes around.  It was just last week that we had peak counts of 30+ warblers and a multitude of species arriving daily.  Now, much of that has passed.  There are indeed still lots of birds around, and the last wave is coming through.  Late warblers, such as Mourning, Wilson’s, and Connecticut are sneaking in the underbrush, while late Flycatchers, like Olive-sided and Alder are calling in the early morning swamps.

Red-winged Blackbirds… once streaming by the thousands, are now a couple dozen.  Almost an anomaly to still see them. Why are they so late?  What held them back down south?  We peaked with 19,000 blackbirds on March 24.  Today, just 14.

250,000 birds! … but not done yet.

The longshore flight continues.  Despite the warming weather, leafing trees, and all the signs of Memorial Day and the start of the summer season, there are still thousands of birds that will be logged from the platform before we call spring migration finished.  Today’s count of 2,295 birds helped push the season count to 250,000 birds.  A far cry from last year’s 428,000 birds.

Today’s 62 species and yesterday’s 87 only brought in two new species for the year.  Those being Yellow-bellied Flycatcher and Mourning Warbler.  Add these two species and we’ve now logged 221 species from the site this year.

Warbler Mania

The Indiana Dunes warbler peak can be manic, yet subtle.  An explosion of sounds and active motion in the bush and overhead.  You look to your right and left, but see no others.  You’re left with fish tales to tell of warblers dripping from the trees.  No elbow to elbow crowds, like seen in other state birding sites.  We won’t deny the appeal of the birder networking and many eyes or shared bird sightings going on at the more known birding sites, like NW Ohio.   Yet here, one can sit in silence, enthralled by the new songs coming from each tree, all performing their songs for you!  Now, crap… can you remember which warbler makes that sound!?

This past weekend, May 17/18 brought the true peak for warblers this season.  Ken Brock writes,

Perhaps no group of birds generates more excitement among birders than the wood warblers…   Accordingly, for many birders the warbler migration constitutes the very quintessence of birding.”

It was indeed written Saturday that the tall trees were dripping with warblers.  No reason to stay at the longshore tower to watch for migrating birds.  One could set up anywhere in the park and watch a parade of feeding warblers zip, jump, dive, and chase after emerging insects.  The temperatures were perfect for active feeding throughout the day.  Winds were light, but felt good in the sun.  The following chart shows all of the warblers that were reported by various birders, eBird reports, the longshore tower, or from the Dunes Birdathon team this weekend.

warbler seenAs mentioned above, it was also the Dunes Birdathon.  It’s NIMBA’s attempt to log as many bird species in the NW Indiana area in 24 hours.  The funds raised help out with various bird related activities in the dunes, such as the owl banding program at the state park.  This year’s team began at 2:30am.  American Woodcock was the first bird heard calling deep in Cowle’s Bog.  The day was joyous.  We quickly hit the dripping warbler wave when we first entered Beverly Shores, just after sunrise.  Tennessee Warblers chipping everywhere.  Redstarts in every understory tree.  Rare for the lakefront, one of the first warblers seen was a Yellow-breasted Chat on Beverly Shores’ far east side near Mt Baldy.  Thrushes would also be common, with both Swainson’s and Gray-cheeked nearly tying each other in numbers this day.

The team birded the state park by 9am and continued racking up good birds.  The park’s Cerulean and Pine Warblers were calling right where they had been.  A quick peak of the park’s nesting Red-shouldered Hawks found mom sitting on the nest.  The Wilson Shelter boardwalk Prothonotary Warbler show was still on.  Here, visitors have been treated to one of the biggest show off warblers.  Mom and Dad Prothonotary continue to gather nest material and build their box full of grass and moss right in front of everyone with no regard for distance.  Today, they would be busy on the ground searching for last minute nesting material.  We savored the sight for a moment, then moved on for more birds.

The late afternoon meant new birds and new habitats.  Kankakee Sands provided many fillers, including the needed grassland sparrows, Bobolinks, Dickcissels, and meadowlarks.  A surprise Osprey in a small fishing pond helped with numbers.  Finally, Willow Slough would give us the bird of the day… an adult female Red-necked Phalarope in full breeding plumage.  A rarity anywhere in Indiana in the spring!

With light fading, our team raced back north to the Grant Street Wetlands.  Yellow-headed Blackbirds still proclaimed their territories, while nighthawks and a single Black-crowned Night-Heron flew by.  Wanting just one more bird, the team drove the growing darkness and had just enough light to see the local Bald Eagles sitting on their nest along the Little Calumet River.  Finally dark, the day was bright!  165 species were seen.  A new record for our little team.

Thanks to all that pledged.  Final numbers and pledges are still being added, but we look to have raised over $1,500.00 yesterday for bird conservation in the dunes!

Not to be outdone.  The bird tower also logged some good birds for those that visited.  Over the past two days, a couple new season birds were seen.  Sedge Wren and Ruddy Turnstone are both good site records.  Also worth noting this weekend were a single Merlin, a couple American White Pelicans, Common Loon, Great Black-backed Gull, 295 Chimney Swifts (Sunday),  and a well seen Lark Sparrow.

Warbler High Gear

It’s been a few days since any update, but weather has been up and down lately.  Sometime this week we passed the statistical peak for warbler migration in the dunes.  The cooler weather and rain showers have no doubt delayed it to the point where the peak may occur this upcoming weekend.  Perfect timing for those wanting to get one great weekend of birding in before the Memorial Day weekend brings it’s traditional swarms of beach goers, trail stompers, and general loud picnicking.

There were a few good counts done early in the week and we continue to have new arrivals filtering in.  Among those new arrivals this week were: Great-horned Owl (first tower bird of year), Gray-cheeked Thrush, and Eastern Wood-Pewee.  Also new in the dunes area were reports of Wilson’s, Canada, and Connecticut Warbler in addition to the season’s first Olive-sided Flycatcher.  Balance this with still double digit counts of Yellow-rumped and Palm Warblers, and it’s a good sign that the peak is going on now and high species counts are possible.  From the tower site, we’re only 4,000 or so birds away from hitting 250,000 birds for the season!

Let’s hope high species counts are possible!  The Dunes Birdathon is this weekend and NIMBA is pushing to raise more than $10 for every species of bird found in NW Indiana tomorrow!  The group will start at 2:30am and won’t stop until the sun sets on Saturday.  There is still time to pledge here.  Consider making a tax-deductible donation for bird activities and research in the dunes!

If you’ve missed some birds lately, here’s two new videos of some of the birds we’ve been seeing the last few days in the dunes.

Today was an important day.  It’s the day before the Indiana Audubon Big May Day count.  It’s also the day before International Migratory Bird Day.  The weather patterns now may dictate the birds we can log tomorrow.  After being nearly a week behind schedule, some amazing winds have brought 4 excellent migration nights and each morning has shown promise of more and more birds.  the tower site is not only producing, but so are nearly every inland area of the dunes.  A great example of migration catching up was the 22 Common Nighthawks observed today feeding over the back dunes (see the video below!).  Most dunes area birders won’t see their first nighthawk for another week or so.

To celebrate International Migratory Bird Day, birders will be out scouring the wetlands, high dunes, lakes, prairies, forests, and more.  The state park has several birding options for anyone looking to enjoy the great peak of migration and hopefully some nice weather.  A warbler bird walk will be offered at 9:30am, at the state park nature center.  From 1:30pm-4pm, it will be an afternoon for the birds.  There will be live bird banding, bird crafts, activities, and even some bird prizes for the young birders.  Visit the nature center for part or all of the time.

To allow for adequate rest, today’s highlights will be truncated.  But, with the morning downpours, shorebirds took advantage to move along the beach.  There were a few notable annuals that arrived today, but the rain brought no significant longshore flight.  New birds today included Semipalmated Sandpiper, Sanderling Baird’s Sandpiper, Dunlin, Dowitcher spp, Common Nighthawk, Willow Flycatcher, and Franklin’s Gull.  The morning ended short with 1,304 birds, making up 69 species.

Inland, warblers were everywhere after the rain falls.  Landon Neumann was kind enough to report a Kentucky Warbler on Trail 2 this morning.  Several other birders were able to see or hear it.  Kentucky Warblers, while more common down south, are much rarer in the dunes.

Will we see you tomorrow?
