Mystery Bird photographed at Smith Point Hawk Watch, Texas (by Joseph Kennedy)

I am not the type to correct people on the internet or play "bird police", but a few people have asked me to clarify the ID of the bird on this post (below). I refrained, but someome asked me just recently, so I decided to simply post the link and have others chime in. But, I will certainly respond if asked...and will confirm the ID. If the bird was identified correctly, I wouldn't bother posting, so one big hint is that the bird in the link is not a Swainson's Hawk as it was identified by the respondents and the quizzer.

Paramotorists claim 'Super Dell' chased, kicked bird in flight

on Tuesday, April 9, 2013 

UPDATE:
The video was removed from youtube this afternoon with a note on the video claiming:

THIS VIDEO IS NO LONGER AVAILABLE DUE TO A COPYRIGHT CLAIM BY DELL SCHANZE

Here is a screenshot that was still available:

"Not-so-super Dell's foot and a Barn Owl he attacked."

I posted this to the UBIRD listserv last night, but wanted to have it reach a broader audience.  This was on KSL.com last night, and has been all over the local news the last 24 hours. Dale Shanze is a failed businessman, humiliated wannabe politician, gun-nut, and pretty mush just a despicable human being.  If the previously mentioned things weren't obvious enough check out the video below that surfaced this week of him chasing a Barn Owl for over 7 minutes in his para-motor-whatever-the-hell-this-contraption-is.

Since the youtube video was pulled I am now linking to the KSL video:



Aside from this, he was previously seen chasing gulls along the south shore of the Great Salt Lake, and last year I watched as he chased hawks around at Point of the Mountain.

I hope this ape gets what's coming and slapped with a fine, and jail time.

April Washington County Roadtrip

Mt. Nebo still covered in Snow in Northern Utah.
We traded snow capped peaks for desert river bottoms this weekend.

Sam and I decided to escape the rains in northern Utah this past weekend and head to Washington County.  We left Friday after work stopping at Chicken Creek Reservoir in Juab County along the way.  If you've never been I highly suggest this as a stop point on the way south on I-15 at Exit 207.  In the spring and fall (if there is water) shorebirds and waterfowl can usually be found in decent numbers, and Friday night was no exception.  Several thousand ducks were on the water, most notably 5 GREATER SCAUP.  A number of other winter species were lingering as well.  A first of year (FOY) CATTLE EGRET was on the north end where the mudflats are.  Also here were numerous AMERICAN AVOCET and a handful or BLACK-NECKED STILTS.

First Cattle Egret of the year at Chicken Creek Reservoir

Back near the outflow a GREAT-TAILED GRACKLE cruised over the road, and around 200 CLIFF SWALLOWS were circling.  We hopped back on the interstate and sped south to St. George.  We ended up on the slope around 11pm.  It  was calm, dusty, dark, and silent.  No poorwills were seen on the drive out, and none heard all night.  The less than 1/2 moon didn't crest until around 4:00am keeping it very dark out all night.  We slept in the back of the truck, watching the stars in the crystal clear sky.  It was dead quiet, no birds sang or called till almost 6:00am.

Sleeping arrangements on our first night on the slope

The morning started with the usual BLACK-THROATED SPARROWS singing out int eh desert. An occasional HOUSE FINCH flew over calling, and several MOURNING DOVES were cooing in the distance.  I left Sam sleeping and hiked down into one of the draws where the sparrows were going nuts.  The cacaphony of WHITE-CROWNED, BLACK-THROATED, and BREWER'S SPARROWS was unbelievable.  The whistles, buzzes and musical notes were filling the draw.  The sound was incredible so I had to get a recording.  I pulled out my camera and set it to video and started recording.  It would be an awesome recording--except for the fact that I didn't realize until 36 hours later when I got home and realized that the hour of video--comprising of 20 different species songs, was only recording video--and not sound.  What a rookie mistake--I had set the camera to no audio earlier in the week recording some ducks, and never switched it back on.  So the Rufous-crowned Sparrow, Black-chinned Sparrow, Painted Redstart, House Wren, Cactus Wren, Lucy's Warbler, Black-throated Sparrow, and a slew of others will have to hopefully be captured again... Instead I was left with photos of the birds I was able to get good looks at, and blurry fuzzy videos of leafs with no singing birds to be heard.

After breakfast and packing the truck, we drove across slope towards the ranch.  Birds were few and far between.  A small group of LADDER-BACKED WOODPECKER moved passed the car, while CACTUS WREN, LOGGERHEAD SHRIKE, and HOUSE FINCHES were seen occasionally passing in front.  One NORTHERN MOCKINGBIRD flew by in the distance, and a TURKEY VULTURE posed nicely in a dead Joshua Tree alongside the road.

As we came into the wash, I got my first look at the ranch in full bloom glory.  From mid-March till October this green swath in the middle of the northern tip of the Mojave is a welcome site for visitors and birds alike.

The oasis in the desert, Lytle Ranch Preserve

At the Ranch I pulled in to find Steve and Cindy Sommerfeld talking with the caretaker. We chatted for a few then headed off up the ranch.  It was rather quiet for a nice spring day.  LUCY'S WARBLERS were singing throughout the walk, and several FOY BELL'S VIREOS could be heard whistling as well.  An occasional ASH-THROATED FLYCATCHER chirped from the trees, and multiple GREATER ROADRUNNER could be heard singing from the brush.

Near the end of the ranch property just past the monument a SUMMER TANAGER called from the trees.  We spotted a single and early HAMMOND'S FLYCATCHER, as well as a COOPER'S HAWK at a nest.

Me at the end of the road at Lytle, 1.25 miles from the main parking lot.

Walking back down the ranch I had both Yellow-rumped and Orange-crowned Warblers, and a FOY singing YELLOW WARBLER.  And although not a bird, I got a decent photo of a "Desert" Black Swallowtail in one of the fields.

We met up wit the Sommerfeld's on the walk back down and shared the few sightings we had.  We headed over to the hummingbird feeders by the trailers which were inundated with BLACK-CHINNED HUMMINGBIRDS, and at lease one male ANNA'S HUMMINGBIRD.  I only saw one COSTA'S which was displaying near the parking area when we left.

At the parking lot as we chatted before taking off, the best birds of the day flew over.  3 Fighter Jets from Nellis AFB came flying over the wash about 150' off the ground.  They came out of nowhere, almost silent until they were right on top of us, at which point the ground shook as they passed, and were gone as fast as they came.  I wondered if these were F-22s because of how fast and quiet their approach was.  It was crazy having them pass so close over, and a first for me at the ranch.  I have had helicopters, crop dusters, sight seeing planes, a UFO (ask me about it sometime), and even an ultralight flyover, but these were the first fighter jets.

After the jets, we checked for black-hawks further down the wash but missed out. We headed back across the slope, stopping at Utah Hill where a FOY GRAY VIREO was singing in the Junipers.  From there we headed back through town, and then out to Zion to do some hiking.  We planned on just walking the river walk Saturday night, then Angel's Landing Sunday morning, so we took the bus to the Temple of Sinawava stop and did the short hike to the end and back.  Birds were scarce.  A handful of SONG SPARROWS, and a flyover TURKEY VULTURE and GOLDEN EAGLE were it.

Back at the bust stop we walked down the road where HOUSE WRENS were busy singing up a storm.  A HAIRY WOODPECKER could be heard chattering and later seen drilling on a dead snag.  UP on the hillside a little ways down the road I heard the repetitive whistling of a PAINTED REDSTART.  This song really stands out when there are no other warblers around in early April, which was one of the reasons I wanted to hike around here and look.  Later on in the spring, I have a hard time picking it out form the chorus and constant whistling of Yellow Warblers everywhere along the river.  I captured the song--but alas got nothing since my sound recording was turned off--brilliant move Avery.

I text Rick Fridell a little later asking when the last time he had one in the canyon was.  I had a couple in 2010 at the Temple and Emerald Pools, but couldn't recall and reports form 2011 or 2012.  Rick confirmed that there hadn't been any the previous two years, but shared that he had also had one singing just 2 days earlier nearby along the river walk--hopefully a good sign for this breeding season!  We hopped on the next bus down canyon and took it back to the Visitor's Center.  We took off to look for a place to camp, and as we drove through Springdale there were 6 TURKEY VULTURES circling over the Virgin River.  There were also numerous swallows including my FOY VIOLET-GREEN SWALLOW, and several first WHITE-THROATED SWIFTS.

We checked a camp site that friends recommended but due to the proximity to the road and how dusty things were we set out to find some place else.  My favorite spot along the Virgin River at Mosquito Cove has been closed for 3 years now due to flooding, and I don't think its ever going to get reopened.  So I remembered somewhere off the beaten path where I had seen people camping before and checked it out.  Sure enough we found a great spot by a creek and made camp for the night.

Lower Kolob Creek

Sunday I woke to singing JUNIPER TITMOUSE, LUCY'S WARBLERS, and BEWICK'S WRENS.  After breaking camp we headed towards Zion for the days hikes, but Sam wasn't feeling great so after looking at our options we scrapped the park.  It wasn't a complete loss, as an exceptionally early WESTERN WOOD-PEWEE was singing from the trees here.  Just wanting to take it easy we drove towards St. George, stopping to try for some sparrows in Dalton Wash. It was a smorgasbord of sparrowy-goodness, with great looks at BLACK-CHINNED, Black-throated, LINCOLN'S, plenty of White-crowned, and a very chatty, but not so abiding RUFOUS-CROWNED SPARROW.  I recorded it calling--but again--nice one with that volume switch Avery.

We stopped at Tonaquint Park for the obligatory ABERT'S TOWHEES, and not much else.  From there we checked out Gunlock State Park.  Along the way we almost saw a GREATER ROADRUNNER meet its maker flying across the road (ironic I know).  The car in font of us came within inches of making the awkward creature roadkill.  I needed a photo for the photo big year so snapped a crappy shot of it running up the hill not knowing when I'll see one again this year (they seem to come in waves--none last trip plenty heard and one seen this trip).

Greater Roadrunner near Shivwits

At Gunlock were numerous EARED GREBE, and a flock of AMERICAN AVOCETS on the water.  Again we check fro Black-Hawks, and despite others reporting them already this week, we missed out.  From here we drove north to Beryl Junction where a lingering ROUGH-LEGGED HAWK was perched along the road.  After that the trip back was uneventful--oh except for the flat tire near Cove Fort that couldn't be fixed.  That was a fun hour wasted--that along with the rush hour like traffic coming back to Salt Lake made for one of the less fun drives back from St. George.  But overall the weekend was great and I can't wait to hopefully get back down there real soon.

By end of trip we tallied 100 species for the weekend.  A respectable number of birds given where we went and how un-birdy two of our major stops were.  Now to double that number plus a couple more--in one day here in about a month and we'll really have something good going on.

Henefer Lek Madness

posted by Tim Avery at
on Tuesday, April 2, 2013 

On Easter Sunday, Sam and I decided to take a drive out to Golden Spike just to get out of the city.  I talked her into heading that way via East Canyon and the Henefer Greater Sage-Grouse Lek.  We left Salt Lake shortly after 6am and got to Henefer before the sunrise. I arrived a little later than I had hoped, but was shocked at what I saw when we hit the Summit/Morgan County line.  There were 10 female grouse along the south edge of the road in Summit County.  There were no grouse in the road, but on the north side of  the road in the area where I normally watch the grouse display were 8 vehicles parked up to the fence .  There was one van on the south side of the road where for years we have parked and watched the birds.

More vehicles than I have ever seen at the lek, parked right where normally birds are displaying.

I pulled off to the south and for a moment sat confused and befuddled.  Why were all these cars parked where the grouse often displayed?  I thought about parking where I normally would by the corral, but then I would be facing no birds, and have a wall of vehicles blocking the birds that were in the fields to the north. Instead I pulled in behind the convoy of folks that were presumably mostly photographers--there was a row of 500+mm lenses projecting from windows. I wondered how many of the folks were here for the first time and jsut following the lead of other vehicles.  I had never thought to park on this side of the road, becuase it was apparent when you arrived most mornings that the birds were on the road. I was upset that in the past I could watch these birds form as close as 20' and see their display up close.  Now the closest birds were over 150’ out into the field

The "sage specks" barely visible at 500mm in my view finder

As I sat there longer I had mixed feelings.  For one the birds were displaying out in the field, and there were plenty of males and dozens of females.  Because they were out in the field, they weren’t on the road, meaning they weren’t going to be killed while trying to mate.  It was a silver lining.  But at the same time it was not the experience I had come to expect up here.  As with previous posts about Henefer I always have mentioned parking as far to the south and east as possible, but in the case of this morning everyone was as far north as they could go, north of the actual pull off in an area I would consider off limits to vehicles.  It was directly where I have watched birds displaying year in and out.

 This male grouse had plenty of admirers... maybe the fields are the best place for lekking...

Don’t get me wrong, I fully expect people who want to see and photograph wildlife to go to places like this and enjoy it--I am actually all for it.  The more people learn about birds like this, the more aware they might be of our impact on them.  But its hard to watch something change so drastically in just a few years.  My biggest worry is it turning into (and excuse my French), the shit show that Farmington has turned into surrounding the Eagles.    I had several people email me privately, including folks who have visited from Wyoming in the past, expressing their frustration with the situation too.  Some complained abotu the actual people, getting out of their cars, letting kids run around, and even one person letting a dog out of teh car.  I was shocked to hear that.  When I went I saw none of that--everyone was in their cars and being respectful of the birds--it was just where they were parked that had me bothered.  Take a look at the difference a few years makes in how close the birds were...

Here is how close the birds were in 2006:

And again in 2007:

It’s hard to believe those birds were in the same place as my best shot from this morning:

In the end I actually felt like it may what's best for the birds.  I would rather watch them from a distance where they can display safely away from the cars, then watch them get hit by drivers not paying attention.  But if the only reason they are displaying where they are is because cars are parking where they want to display, then that is an issue. When you visit the lek, please be mindful of the birds, and just use common sense.  I still advocate parking to the southeast, and giving the birds as much space as possible--and if you are like me, you probably won't want to head up there on a weekend with the growing crowds.

New Research on Gulls Changes Everything

posted by Kenny Frisch at
on Sunday, March 31, 2013 

For a long time scientists and birders alike have had trouble not only telling one gull species from another, but even knowing whether a certain gull species should even be a species. In recent years the debate has come down on the Herring Gull complex- whether there are 3 different Herring Gulls, or if Thayer's, Herring, and Iceland Gulls should be all lumped as one species or something in the middle.  All of that has changed though.

 Great Black-backed Gulls have strong genes

Stunning new research has shown that almost all gull species to be hybrids of Great Black-backed Gulls and unbelievably, Little Gulls.  Mitochondrial DNA or mtDNA taken from a host of former gull "species" show genes in all gull species that be traced back to both of these parent species.  Backcrosses and breeding among the hybrids have resulted in the wide range of gulls we see today.  Gulls with more Little Gull genes are more of the smaller gulls (like Ring-billed and Franklin's) whereas gulls with more Great Black-backed genes tend to be larger (like Glaucous and Western).

Opposites attract when it comes to Little Gulls

I'm sure of all of you have many questions, just as I did upon my first reading of this research.  What about mantle color?  It turns out that Little Gulls and Great Black-backed Gulls share a common ancestor, one that most likely had a paler back.  In both the species, the ancestral genes are turned off, however when they hybridize, these ancestral genes can be expressed, leading to the wide variety of mantle colors we see today.  What about their breeding ranges?  It's true that both species breeding ranges don't overlap now, but it turns out that right after the last Ice Age, Little and Great Black-backed Gulls shared a common breeding ground where the hybridizing started. It also seems like there may in fact be no "pure" Great Black-backed Gulls or Little Gulls given the amount of cross breeding.

It makes sense that Sabine's Gulls are just goofy hybrids

There are still many questions to be answered, mainly if all these new hybrid gulls are stable hybrids and one day may be considered new species.  Given the amount of hybrids we see each winter in Utah, I think we are a long way away from having anything more than a handful of true gull species.

Personally, I am not looking forward to losing 18 species off my life list, but science is always moving ahead and we birders just need to catch up.
