Back on June 11th, I was biking down a Fort Bragg back-alley along the GP property balancing a small Zappa's mocha coffee in one hand heading for my bus stop. Out of the corner of my eye I spotted a small butterfly along the fence. I put on the brakes and laid the bike and mocha down (without spilling a drop) and was able to get this picture.
By small I mean smaller then a dime with the wings folded. Upon reviewing the picture I thought this was going to be an easy butterfly to identify. I should never think that. In Kaufman's Field Guide to Butterflies of North America I first noted the Acmon Blue with it's large range in the west and thought that had to be the one but just below it was the Lupine Blue that had a smaller range that also included the Fort Bragg area. Kaufman states that the classification of these two butterflies is controversial. “The widespread forms may be Lupines, not Acmons, or they may make up multiple species.”
I submitted the picture to the experts at Butterflies and Moths of North America and got this response.
There is no information provided that will resolve whether this is an Acmon or Lupine Blue…it could be either.
Two weeks later on the bluffs overlooking Virgin Creek Beach I was able to get a few pictures of this butterfly.
This time I was able to get the bottom of the wings and thought that might be the key to identifying this butterfly. I knew that once again I was up against the Acmon/Lupine problem. I received this response.
There is no upper view or other information provided that would allow an ID except someone familiar with that locality-Ken Davenport
On July 13th, while birding at the Little River Airport, a totally different environment, I found several of these butterflies and got pictures of both the upper and lower wings.
What was the response from the expert?
Without knowing the host plant and the locality myself, I can't say which species it is. I suspect acmon but can't be sure. Maybe someone else familiar with that locality will know so I will leave the submission open to review.-Ken Davenport
Currently all three of my submissions for this butterfly remain pending waiting for a local expert to weigh in. It seems that I will now have to become a botany expert.To be fair to Ken Davenport he apparently lives in Bakersfield and doesn't know this area. At least I got a “possible” answer. I actually believe that he's correct. Kaufman states that the Acmon Blue flies “spring to fall” with 2-3 broods. The Lupine Blue “flies spring to summer depending on locality and elevation” with mainly 1 brood. Butterflies fly earlier at lower elevations. Shapiro's Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions states that the Lupine Blue flies generally in late spring. If that's true then this Acmon/Lupine Blue that I found near the end of Ward Ave. on July 23rd in most likely an Acmon Blue.
The later I find this butterfly the chances are that it's an Acmon Blue. That's my theory anyway. Shapiro has this to say about the Lupine Blue.
Of all the species listed in this book, this is the one whose status in our area is most uncertain. It has been recorded from Santa Cruz and Santa Clara Countries, but whether the specimens are correctly identified…remain to be determined…The situation is so fluid that we had best wait for Paul Opler to complete his revision of the group, now in progress, and hope that it clarifies these questions…Have fun!
That is why butterflies are so frustrating! The day I found the Acmon/Lupine Blue at the airport was a four butterfly day, something that is rare there. All of the butterflies were in fresh condition which indicates to me they had just emerged. There was no frustration in identifying them. This Painted Lady is probably part of a second brood since the airport was covered with them in the spring.
A Mylitta Crescent.
And a California Sister that flew up to me and gave me great views.
This American Lady recently settled down on some flowers on my deck. It is only the second one I've seen in Mendocino County and both have been at the Woods where I live.
Let's talk a little about birding. The big birding news, at least for me, concerns birding at the Little River Airport. Readers of this blog might remember an incident at the airport after I reported a Mountain Bluebird last year.
Sat. 6/14/14–This morning I was doing my usual birding at the Little River Airport and happened to start a conversation with the airport’s manager. I started the conversation with the announcement of a rare Mountain Bluebird last Sunday. He said he knew all about it and proceeded to tell me several stories about birders chasing it. One birder after watching plane activity proceeded to walk out on the active runway. Another group of birders decided to form a car caravan and drove out on the taxiway, stopped on it and got out and set up their scopes. He related a plane on the taxiway having to stop because of people in it’s way.
Apparently birders are not the only idiots there that do strange things at the airport. In talking to pilots I've heard many scary stories about people walking their dogs, riding their bikes and just having a good time out on the runway and in the hanger area. I have humorously called the airport my “playground” because of a 2005 newspaper article That stated,
As for the airport property incursions and the lack of enforcement against trespassers, the LRAAC wants an approved policy the Sheriffs department can use to disperse illegal assemblies, with guidelines on when to arrest and to prosecute those involved. Airport Manager Thorpe conveyed their reluctance to respond to calls without a clear policy for handling complaints.
The letter states, Now there is a mixture of teenagers and older people who have made the airport their playground. They ride motorcycles and off-road vehicles by developing their own unauthorized access roads and paths.
Sometimes people trespass on the airport in pickup trucks and park near the runway to drink at night. Then they smash large numbers of empty bottles by throwing them into the runway. The broken glass is a real danger to landing aircraft.
When the airport supervisor approaches these trespassers, their typical response is, There are several of us and one of you, what are you going to do about it?
The letter indicates the committee strongly supports increasing efforts to block runway access by implementing the CIP security fencing project, as soon as possible, and placing better No Trespassing and Warning Federal Offense signage around the perimeter.
On Jan. 9. numerous shots were fired on airport property. Two abandoned cars were discovered smashed with large amounts of garbage dumped where bonfires and disturbances have been taking place. On Feb. 2 a parent refused to take his children, who were riding bicycles, off the airports active runway, or to leave when ordered to by the airport supervisor.
The Little River Airport is now trying to make the airport idiot-proof. They have already installed gates around the terminal that will solve much of the problem. There has been a proposal for an Airport Traffic Area where you would need permission to enter from the airport manager.
On the rest of the property you will have to sign a Little River Airport: Permission to Hike on Airport Property Form. This form will indemnify Mendocino County from any damages or injury that might occur on the property and that you could lose this right to hike on the property if you enter the Airport Traffic Area without permission. The airport property is extensive at roughly 564 acres.
For me just stepping across Little River Airport Road puts me on airport property. The light green section (C) is where the locals are trying to save a valuable section of Redwoods.
I have been in negotiations with members of the Little River Airport Advisory Committee about boundaries for the Airport Traffic Area and certainly I'm making every effort to stay on friendly terms with the pilots and the airport manager. I know two members of the committee. They are mostly concerned with the idiots that are out on the taxiway and runway and have no problems with the berry pickers, mushroom hunters, dog walkers (on leash), and at least this local birder. Stay tuned.
The actual birding here in Mendocino has been slow but is beginning to pickup. The shorebirds have started to return. The Elegant Terns are returning in good numbers which indicates a warm ocean. With El Niño conditions expected we are looking forward to an interesting fall.
A Mute Swan turns up occasionally. Here it is at Virgin Creek and flying over Fort Bragg.
Heermann's Gulls arrived early and are here in numbers I've never seen before.
But the most bizarre thing that has ever happened to me was during a recent SOS survey at Virgin Creek Beach. I had notice a strange bird calling and couldn't locate where it was coming from. The source of the call was a couple, Mike and Paula approaching me, who were out walking their Aplomado Falcon.
This is a Peruvian Aplomado Falcon, F. f. Pichinchae. The couple, both licensed falconers, had purchased it in Washington from a breeder. They had previously had a Gyrfalcon but found it too large for the area, whatever that means.
There is some controversy concerning falconry. There are those who believe that birds should fly free if capable. There are others, mostly falconers, who feel that falconry is a benefit. Wikipedia of course has an article on falconry. The art(?) of falconry is ancient with the earliest accounts dating to approximately 2,000 BC.
Falconry was largely restricted to the noble classes due to the prerequisite commitment of time, money, and space.
From what I have read it's still a sport for people with money. There are several groups of falconers that have been created. One of these is the North America Falconers Association.
Our Mission and Purpose: Is to improve, aid, and encourage competency in the art and practice of falconry among interested persons; to provide communication among and to disseminate information to interested Members; to promote scientific study of the raptorial species, their care, welfare and training; to promote conservation of the birds of prey and an appreciation of their value in nature and in wildlife conservation programs; to urge recognition of falconry as a legal field sport; and, to establish traditions which will aid, perpetuate, and further the welfare of falconry and the raptors it employs.
Falconry is one of the oldest methods of hunting. Eagles, hawks, and falcons are used by falconers to pursue and catch quarry for food. When the Peregrine Falcon became endangered due to the widespread use of DDT and other pesticides, falconers were instrumental in organizing the successful effort to recover the species.
Audubon doesn't seem to have a problem with falconry looking at it as another help with conservation. Audubon groups seem to welcome the falconer at their meetings and use the event as an educational tool.
I could not find a group that had as their main mission the banning of falconry but in Great Britain efforts were made by the Royal Society for the Protection of Birds and other lobby groups to have falconry outlawed, but these were successfully resisted.
My biggest concern with falconry is that falconers are allowed to break the law.
The Migratory Bird Treaty Act of 1918 (MBTA), codified at 16 U.S.C. §§ 703–712 (although §709 is omitted), is a United States federal law, first enacted in 1916 in order to implement the convention for the protection of migratory birds between the United States and Great Britain (acting on behalf of Canada). The statute makes it unlawful without a waiver to pursue, hunt, take, capture, kill or sell birds listed therein (“migratory birds”). The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs and nests. Over 800 species are currently on the list.
The U.S. Fish and Wildlife Service issues permits for otherwise prohibited activities under the act. These include permits for taxidermy, falconry, propagation, scientific and educational use, and depredation, an example of the latter being the killing of geese near an airport, where they pose a danger to aircraft.
To have a bird of prey just because you want one seems to me a violation of the intent of the MBTA. When you read the California Regulations for falconry it get worse. Things like this disturb me.
A Master falconer may possess any number of raptors except he/she shall possess no more than five wild-caught raptors for use in falconry at any onetime, regardless of the number of state, tribal, or territorialfalconry licenses in possession.
(3) Raptors may be captured by trap or net methods that do not injure them. The licensee shall identify all set traps with the name and address of the licensee and shall check such traps at least once every 12 hours, except that all snare type traps shall be attended at all times when they are deployed.
(5) The following raptor species may be captured from the wild in California: Northern goshawk (Accipitergentilis), Cooper's hawk (Accipiter cooperii), sharp-shinned hawk (Accipiter striatus), red-tailed hawk (Buteojamaicensis), red-shouldered hawk (Buteo lineatus),merlin (Falco columbarius), American kestrel (Falcosparverius), prairie falcon (Falco mexicanus), barred owl(Strix varia), and great horned owl (Bubo virginianus).
(6) No more than two nestlings of the species allowed for capture from the wild may be captured by the same General or Master licensee during the regulatory year. In no case may all nestlings be captured and removed from any nest. At least one nestling shall be left in a nest at all times.
I will let you form your own opinion on falconry if you care to. The internet is filled with falconers justifying their hobby. One site justifies falconry because of it's cultural and traditional history.
Being a living culture, falconry remains strongly rooted in the past. This aspect has been recognized and accentuated in the UNESCO statement on falconry as Intangible Cultural Heritage of the Humanity, that describes and qualifies it using such expressions as “traditional activity” and „cultural heritage” that is “passed on from generation to generation”, providing “a sense of belonging, continuity and identity”.
There are many cultural and traditional practices that we are trying to end, such as discrimination against minority's, gay marriage and even flying the confederate flag. Not all historical practices deserve to continue.
Another site made this statement in a “moral” effort to justify falconry.
And even if you face falconry from an aesthetic point of view, you will find no contradiction. As far as we know, animals have no thirst for freedom.
How do you justify an argument based on unknown data?
STOP THE PRESS!!
While writing this post I conducted a SOS Survey at Virgin Creek. After the survey I found two new butterflies to add to my Mendocino County list. One was a Checkered White on the bluffs above Virgin Creek Beach.
The other was a West Coast Lady at Ward Ave. I have now seen all the Lady's in Mendocino County.
And I finally got a picture of an Acmon Blue. If you still remember the beginning of this post, my theory was right. This is my first picture of a male. It was on territory chasing away another male.
The expert at Butterflies and Moths of North America accepted my submission as an Acmon Blue.
You are right, based on date this should be an Acmon Blue. And familiarity with Acmon Blues leads to improved ability to tell the 2 apart, but maybe not with nominate Lupine Blues which occur in that part of the state-Ken Davenport
So I guess I found three new Mendocino County butterflies. Butterflies are now only slightly less frustrating!
The butterfly counts not months but moments, and has time enough.
