Butter Butt Influx

Happy Easter.  No longshore flight officially is taking place today due to the holiday. However, Saturday, April 15th brought a very warm day to the dunes and is worth reporting.  Overnight spotty storms and south winds created a warm wind at dawn that increased through the day.  Like a good Saturday does, a contingent of bird enthusiasts joined our counter at the tower for an excellent morning of longshore flight.  By noon, temperatures were in the low 80s.  The group of birders logged 6,942 birds from 74 species.  Here are the highlights:

Little movement occurred over the lake, as the majority of waterfowl appear to have moved through.  Loons however, are still present.  3 Common Loons were seen on the water, but more significant was a good flock of 18 Red-throated Loons that took off from the water as a fishing charter boat went by past the park.

Pine Warbler from Friday’s count.

New for the season were House Wren, Palm Warbler, Orange-crowned Warbler, and White-throated Sparrow all right on time for the year!  The early wave of neo-tropical migrants was evident today, as the first rounds of typical early season warblers passed in full force Saturday.  37 Blue-gray Gnatcatchers was a significant early season movement of the the little buzzers.  The butter butts, aka Yellow-rumped Warblers, made a significant flight in front of the counters, often moving at eye level throught the nearby dune oak canopy, and landing briefly before pushing on towards Chicago and eventually Canada.  348 butter butts went by.  It wasn’t a state top 10 count, but still quite good.  In addition to the previously mentioned Palm Warbler, Pine Warblers moved through in excellent numbers too.  The day’s 23 Pine Warblers is the highest Pine Warbler total in the five years of official longshore surveys, and likely the state’s second highest single day count.

Likely due to the stronger wind speeds, the thermal development suffered and the day’s hawkflight failed to really materialize.  Only 49 raptors went by the tower.  Osprey and 5 Broad-winged Hawks were the highlights for the birds of prey.

Saturday’s full count can be found on ebird here.  The weather outlook looks good for some upcoming counts, so expect the birds to keep coming!  The season total species count so far is 137 species.

Migration Returns!

After a nearly two week hiatus, migration returned in style today.  It’s only fitting that this occurs today, as we write our 200th blog post since we began documenting the longshore morning bird flight over 3 seasons ago.  With warm south winds, conditions were ripe for the first waves to enter the dunes.  Conditions were also ideal for thirsty birders, parched from the dry spell we’ve been facing.  A full contingent tested the space limits on the longshore tower today.

Before midnight, light north winds gradually shifted east, then southerly allowing for what we hope is a teaser of a couple more powerful flights of birds.  If the bird represents a major baseball team, likely we saw multiples of them!  Bluejays… yup, over 1,000.  Orioles… yup, 30 to be exact.  Loons… ok, yep, we had a few of them too!  It was a morning with annuals galore, as we jumped to a daily total of 4,631 birds, represented by 90 species.

New for the scene this year were American Golden Plover, Eastern Kingbird, Yellow-throated Vireo, Warbling Vireos, Nashville Warbler, Northern Parula, Yellow Warbler, Palm Warbler, Black-throated Green Warbler, Rose-breasted Grosbeak, Indigo Bunting, and Orchard Oriole.

Bluejays staged their first big push with 1,311 birds.  Over 1/4 of all birds today were Bluejays!  Goldfinches also put in a good movement with over 500 seen.  Gnatcatchers were not far behind  The 72 seen sits comfortably in the state’s top 10 count.  A few banding nets were also strung today, hoping to catch a few of these birds.  They’ll be up through the Indiana Dunes Birding Festival, and today had a nice pair of Brown Thrashers that a few folks got to see up close.

With the most recent north winds, it’s not surprising that we have a few late migrants too.  Most notably some lingering juncos and tree sparrows.  Black-backed Gulls in May are also getting quite late.

Another good day looks in store for Sunday.  Until then, here’s a partial list of the main highlights from today.

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.

Lake Michigan Neotropical Madness!

May 8 was the little longshore flight that could.  Under steamy conditions and a strong south gale, passerines streamed out of areas to our south in search of bug infested zones to raise their young.  May 8 was also the longshore flight that just came short of some record breaking counts.  To come second or fourth place is still impressive.  It also becomes a nice contrast.  Today was not too different than yesterday, but the birds were again diverse and different.

Steamy counters, May 8, 2014.

By dawn, it became obvious that a massive Blue Jay movement of near count was underway.  blue Jays would cloud the sky, going west to east.  Unlike yesterday, warblers were only an occasional chip note overhead.  In place of warblers were buzzy zip notes of Indigo Buntings.  Orioles gave full song as they flew past an occasionally land on a nearby cottonwood tree.  Again and again, orioles would fly by to the thought, “oh, just another oriole…”

First of the season birds included Golden-winged Warbler (first at the site in many years), American Redstart, Yellow-throated Warbler (first in many years, a rare tower bird), Blue Grosbeak, and a great record of Red Crossbill.

But, back to the high counts.  Today’s 7,058 jays makes a new second state record for highest single party count.  Last year, the record was broken with 7,264 on May 1.  So close!  Orioles came in at 243.  The record for the tower is 464, so today’s count, while impressive sits in the top 5 high counts.  Today’s Indigo Bunting count likely also will score in the top 10 when all is analyzed.

Updated Record Results from Ken Brock:
Blue Jay 7058 Indiana’s 2nd largest daily count
Baltimore Oriole 243 Indiana’s 6th largest count
American Goldfinch 960 Indiana’s 20th largest count
Eastern Kingbird 158  Indiana’s 9th largest count

Appreciable numbers of bird counters in the early hours helped with the morning flurry of longshore migrants. Randy Pals counted Blue Jays, while John Cassady twitched for goodies. Brad Bumgardner, Ken Brock, John Kendall and Lynea Hinchman all did a stint atop the platform. And Hal Cohen, the San Diego county Swainson’s Hawk counter, came out from Chicago.  The day ended with 82 species, making up nearly 10,000 birds (9,328).  This is the highest count since mid-April!

Gotta Love Those Flyways!

Last night, as predicted, a large movement of neo-tropical birds moved through Indiana, and brought the most diverse longshore flight of the season.  It was also the first day this season to surpass 100 species in one morning.  Today’s flight brought 2,743 birds of 102 species.

When large flights are predicted, you can also predict large congregations of birders.  As such, there were many eyes out today assisting the counter push past 100 species.  New counter birds for this season were Chestnut-sided Warbler, Blackpoll Warbler, Ovenbird, Prairie Warbler, and Least Sandpiper.  By noon, the warm are was almost sweltering.  The stiff wind prevented any of the colder off-shore water from cooling the dunes.  The forecast overnight is for the dying winds to allow the warm air draw the cooler lake air into the area, but south winds throughout the state will flood the area with more birds tonight.  Tomorrow should be another great flight.  Bring your oriole eyes with you!

Assisting Brendan today was Ed Hopkins, Jeff “Magic Eyes” McCoy, Pete and Nila Grube, and John Kendall.  Don’t forget we’re desperate to keep counting birds. Brendan has really forgotten how to do anything else.  Consider pledging to our Birdathon on May 17 to help fund bird related events and programs at the Indiana Dunes State Park!

Tail Wagging Warblers

Today’s longshore flight brought another good day of migration.  Despite the east winds, with northerly tendencies (especially after noon) the day ended being the best flight of the season and sixth best of all time according to the Grube Magnitude index (65.80 specifically).   88 species, making up 2,790 birds were logged today.  Warblers were the show all morning.

Despite the evening songbird flight being done, many warblers and other nocturnal birds continued on after the sun had risen.  12 species of warbler were observed going over in high speed mode.  These 12 warblers included 1,144 birds.  That’s right… 1000+ warblers were identified from the platform today.  As would be predicted in a season running a week behind, Yellow-rumped Warblers would make up the super majority.  the 924 butter butts would be the state’s seventh highest count.  they zipped past going east by ones and loose groups.  Two other equally impressive (for their species) counts came from Palm Warblers (156) and Nashville Warblers (26).  It was the 12th highest state count for the Palms, and 11th highest for the Nashvilles.  The total warbler count today doubled the cumulative totals thus far this season.

Other notable warblers seen going by included a single Orange-crowned, 12 Black-throated Green, 7 Pine, and 2 Blackburnian Warblers.  Warbler neck is on!  Adding to the diversity today were the season’s first hummingbirds, while juncos and Clay-colored Sparrows flirted with the feeders below.  A real eclectic group today.

We finally will crank into some serious south winds and we expect some good flights to occur for anyone wishing to visit the next few days and into the weekend for the IAS Big May Day Count.  Blue Jays and Warbs should deliver some impressive totals, and birders taking the inland route will find some good variety too.  Already today, other good birds were logged inside the park by birders.  The Trail 2/10 loop is a good start.  The back dunes along the wetland provide shelter and nice control burn areas that allow birds to feast on the forest floor.  The 1/2 mile long boardwalk can bring any bird to surprise you, while the rest of Trail 2 is a peaceful backwoods of wildflower carpets, Cerulean’s galore, and loud drumming Pileated Woodpeckers.  Reports from this area today include Blue-winged Warbler, the season’s first Prothonotary Warbler, lots of Pine Warblers, Lincoln Sparrow,  and some equally impressive counts to rival the tower site.  134 Palm Warblers were seen feeding on Trail 10 today.  This is why our birding trails are better than anywhere else in the state!
