The Olympic Sports



An easy gull to ID.  Yellow legs and smaller?  Black and red dip?  The California Gull
Warning!  This post is about gull ID.  I'll try to make it as interesting as I can. But you've been warned! So here goes......

This gull is definitely a Heinz 57.  An Olympic for sure!
Some species of birds can hybridize freely in the right habitat.  There aren't really any clear examples of this in the human population since we are all human of various colors and sizes. Although, I have heard that the Andean people are unique to the human population as they are shorter with more blood vessels(to keep them warm) due to the higher and colder elevations of the Andes mountains. 


I took this photo from the high elevations of Lake Titicaca on the floating islands of the Uros in the Andean mountain chain.  

I was a terrible birder even in 2008.  A Great Egret 
There may be a secret population of tiny people, about the size of hobbits, somewhere in Asia. Scientists have found bones to back up their claims and some locals even claim to have seen these tiny people in the dense Asian forests. I think I read this from Breitbart News, the world's leading source of fake news. However, last I checked, we are all still human, extra blood vessels and all. 

Dark eye, shading on the head but an all gray back????  Yeah.  An Olympic Gull, a hybrid
 Could humans hybridize with gorillas? Is Bigfoot a hybrid of a man/bear?  I don't know.  Even the thought is disturbing, but I did see some creepy mountain people in Oregon outside of Portland. I'll geek out with some Star Trek examples instead.  
With Leonard Nimoy before his passing who portrayed the popular character Spock
An example of hybridization of the human species would be like Vulcans and Humans having babies.  Spock is the offspring of these two species.  B'elanna Torres is the hybridization of a Klingon and Human.  So, what does this have to do with gulls?

Surf Scoter
 OH LOOK!!!  It's a SURF SCOTER!!!  Anything to distract from the monotonous ID work. It's like a student being forced to do classwork against their will until someone shoots a spit wad across the room at his friend's head. It misses his head and hits the quiet girl in the back row. Now that's WAY more interesting....and funny! And so I have observed that most birders get easily distracted by the other birds popping out of the ocean water. I stand my ground. Gulls are cool! #gullsmatter


I do have moments like this often in class.  While school has changed, the human dynamic is still the same. Information is quicker now with SMART technology 
I have now become the eager "A" student in class raising his hand all the time.  I like this subject. No.  I LOVE this subject. So I try connecting the dots in this simple brain of mine. 



Here's what I know. Gulls can interbreed freely if their habitat ranges overlap.  Some more than others.  And apparently the Pacific Northwest is a hotbed for gulls to hybridize! In the desert southwest, Costa's Hummingbirds can breed with other hummingbird species like the Lucifer Hummingbirds.  Their hybrids are called Costifers. The simple fact is that nature is constantly evolving and that our understanding of the biological world isn't so black and white.  

Is this gull trying to be a Thayer's?!
So it's only logical that hybridization occurs in the gull world.  My issue?  Finding a "pure" Glaucous-winged Gull.  I found my searches to be kinda frustrating at first.  And I discovered that Oregon, Washington and British Colombia are some of the most difficult places to find a "pure" gull.  I love gulls and I've come across a few hybrids here and there, but nothing like this! Most hybrid gulls found along the Pacific coastline are known as "Olympic Gulls".  Apparently, the Glaucous-winged and Glaucous Gulls can hybridize with Herring and Western Gulls.  And they especially hybridize with Western Gulls. This makes gull ID VERY difficult!

a Horned Grebe is a nice distraction
 HORNED GREBE!!!  Oh.  Yeah.  The gulls. So what did I have to do?  Well.  The GWGU is a large all gray bird.  No black on the feathers.  No black on the bill.  No shading on the head.  And pink legs. Easy right? So I'd find a good candidate and then spot black somewhere on the bill or on the wing.  

Too black!  Those end tail feathers should be ALL gray
 Or I'd find one with all the right markings but the head shape and size were all wrong.  With persistence and determination, I found several "pure" Glaucous-winged, NOT Olympic, gulls. 

All glaucous but what's with the shading on the head and the black on the bill???  GRRRR!!! Another Olympic Gull. 
I'll be honest.  The search for this life bird felt dirty.  Only humans can make the natural birding world feel like a segregated nightmare. For those listing in the ABA world, they have to make sure they've got the right gull or they could lose their tick. The challenge and search for this bird gave me a better cultural understanding behind the hybridization of gulls in this area.  It still doesn't shake that nagging question inside my head, "What makes a species a species?"  And why is that question so important to me?!

We've got a winner!!!!!  My lifer Glaucous-winged Gull.  It just took awhile to figure it all out. 
 We are still discovering so much about birds.  Many of the pink-legged gulls share 98 percent of their DNA.  Nature is messy.  It's also fascinating. 


At the end of the day, I've added a new species of bird on that slowly growing life list. The experience behind this gull taught me a lot but there is still so much more to learn. Until next time.....

Geronimo!

California Thrasher!

The great West can be daunting.  It's even more intimidating when one treks the vast desert alone.  I purchased water and all kinds of rations just in case my car decided to act up.  Cell phones don't work in certain areas and the landscape changes from Sonoran desert into the sandy Imperial Dunes near Yuma.  Eventually the driver reaches the forgotten lands of the Salton Sea full of pesticides, agricultural lands and the infamous Sonny Bono wildlife preserve.  Even further, one must cross the great mountains of rock and alpine shrubs.  Then begins the descent into the crowded urban area known as San Diego. I summoned the courage of the great Indian spirit, Chief Geronimo.  As I shouted his name, I took the plunge one last time into the area known as San Diego!


Bushtit

The end of the year would bring me once more back into Southern California to clean up most of the endemics found in this area.  However this trek was made alone since Pat had to work.  The year is winding down fast and I needed to find more birds! So I went into some of the most eccentric places around SoCal.

White-crowned Sparrow
I hit 4 major places.  The Salton Sea. The Tijuana Estuary.  Discovery Lake of San Marcos. And Lindo Lake of Lakeside.

California Towhee
Within the recently burned city of San Marcos, I found an oasis known as Discovery Lake.  There I witnessed mothers running with their children on the trails listening to annoying songs like, "Let It Go!"  Go ahead and click on the link.  I dare you:)  I was trying to listen to the lesser known "California Thrasher" song.  According to birders, it's one of California's better tunes...even topping the Momma and Papa's "California Dreamin!"



Discovery Lake was a pretty amazing area full of incredible birds!  I think I spent the entire morning there birding.  I heard the California Quail but I never saw them.  I heard all the other birds and DID see them.  Sometimes you just have to learn to "Let It Go, Let It Goooo!"  I had that damn song stuck in my head all day!

Wrentit
Another new bird for me was the Wrentit.  I'm never sure about these combo names in the bird world.  So what is it?  More Wren or more Tit?  Either way, I thought it would be harder to ID.  It wasn't.  The call was distinct and the bird was much larger than the Bushtits also found in the area. 

Brants
After getting a visual on 2 out of the 3 life bird targets, I decided it was time to move south to the Chula Vista area for the Brants.  I met up with friends Libby and Bonnie at their place and walked along the waterfront enjoying their company while of course observing the birds!

Surf Scoters
We were super thrilled to spot Surf Scoters.  I don't know why they are so cool, but they are.  Their bill is so strange and colorful!


Scaly-breasted Munia
And then there were these birds!  The Scaly-breasted Munia were almost on every one of my counts this last time.  I would hear them squeek and I'd think, "Are those strange Cedar Waxwings calling?" They can also sound like mice! Then they'd fly up and remind me that they're taking over Southern California.  And as for parrots!  A month ago I reported on the Red-crowned and Lilac-crowned Parrots of Orange County!  Well they are around the San Diego area as well.  I sometimes forget that there are parrots around those parts.  When it finally registers inside my tiny little brain, they are flying over my head!  



This was my road trip song to keep me going.  I want to let everyone know that I'll be catching up with you all soon.  I've been on the road way too much these past two weeks trying to keep up with the end of the 2014 year:) I'll carry on with my report from the other two areas next week. And when I'm feeling intimidated by the challenge, I just have to remember to say, "Geronimo!"

Surf's Up!

Black-crowned Night-Heron
Right now, the watering holes around Arizona are hot with migrating waterfowl from the north.  Birders are rushing to these areas to pick up a rare bird or two for their checklists.  

Thousand of tiny bugs catch the last light of the day.  
Over the past week, I've left work and headed straight away to our local parks and watering holes to see if I can catch a gull, duck or rare goose. 


Ducks and more ducks!  Ring-necked Duck, American Coots, American Wigeons and Domestic Ducks are just some of the characters who show up for their picture.
The light diminishes quickly now.  By the time I arrive to my destinations, I have about one hour to bird before it's completely dark. 

Coachline Pit Ebird Hotspot
In many ways, birding around water areas is very relaxing.  I grab my binoculars and just scan the waters.  Birds float past, fly overhead or just simply appear out of nowhere from beneath the water's surface when I stand in one spot. 


Western Grebe
Recently, Arizona has seen a great number of rare birds zip through the area.  

Clark's Grebe-my first decent photo documentation of this tricky bird.  Note orange colored bill and dark above the eye.  The above pic shows how similar the Clark's and Western Grebes are.  In Pima County, a Clark's Grebe is a rare gem. This bird was seen at Sahuarita Community Lake
There have been amazing birds like the very rare American Tree Sparrow, White-winged Scoter, Purple Finch, Bonaparte's Gull, etc......


When the report of a Surf Scoter surfaced, I drove 2 hours to go find it!  And so I sifted through every American Coot floating around the boat launch until I caught sight of my target bird. 


Say's Phoebe
With the cool temps and even cooler breezes off Saguaro Lake, I sat on a rock and watched my lifebird float past me nearby the shore.  There she was.  Something special.  A gem.

Saguaro Lake
Scoters tend to stay in the deeper waters.  Most people count them with their scopes from shore.  When I heard that this bird was hanging out near the shore, it was a no brainer.  The Scoter at this moment trumped everything else being seen in the state. 

Redhead
I watched this bird chase coots and dive into the water. She was magnificent and made Year Bird 456.  Next time you are at a park, check to see if a swan, duck, grebe, coot, scoter, heron, gull or sandpiper has stopped by.  You never know who is going to show up:)

Female Surf Scoter
While on my road trips this week, I've been listening to Rose Ave's new album.  I can't stop humming the tune to this song!
