It is a Parasitic Jaeger

I saw my first Jaeger on Monday, Mar. 26, 2007. That story is published in my blog Long-tailed Jaeger in Texas. In that blog and the next two, Long-tailed Jaeger 2, Long-tailed Jaeger 3, I published all my photos and discussed why our tour group decided that this was a Long-tailed Jaeger and not Parasitic or Pomarine Jaeger. As you see from the title, we were wrong.

I can now tell you the story of the verification process:
The day after the tour, my husband and I went to Aransas NWR and while we were in the office, the volunteer told us that the office staff was abuzz with the news that a Long-tailed Jaeger or other jaeger had been seen in the refuge. Someone had reported this to Aransas. Also one person of our group had promised the captain, he would report this sighting to the Texas Birds Records Committee (TBRC).

So, naturally, I expected to get a request for the use of my pictures soon. But by Thursday, I became impatient and published my first blog with the other two a couple of days later. Still nothing, no one called or emailed me.

I thought that when an unusual bird was sighted, that the birders from all over the world would rush to come to see it. At least, that's what I read in the magazines. I did hear that the jaeger was not seen on later tours. So hot news this was NOT!

Finally in July, No one had yet sent any information to the TBRC. Well, I thought, I know how to get some answers for my self and sent my story and pictures to one of the leading ornithologists, who had helped me with identification in the past, and his reply in less than a week was this:

"I hate to bring your sighting down a notch but I think this is a Parasitic Jaeger. I'm certain it's not a Long-tailed, which should have the wing coverts and back distinctly paler gray-brown, contrasting with darker flight feathers above, no white on the underwing (flying and turning photo) and a shorter bill. I'm less certain that it is not a Pomarine, but I think the bill is too slender and the pale forehead is typical of Parasitic."

This was his opinion with just a quick look and I am not disappointed, because any jaeger is a life bird for me. (Just change the name on my list and website. It doesn't change the bird!)

Then the next day, I get an email from Darrin Welchert, biologist at Aransas NWR, requesting information. (Some one's ears were burning with these emails and pictures flying through the whatever and reminded them that there had been this HOT sighting in March.) I sent all my pictures to Darrin, who in turn sent everything to the TBRC. This was the middle of July.

A couple of times, I received emails from other birders, who read my blog or saw pictures on my website, telling me that this was not a Long-tailed Jaeger but I replied that I would correct everything when it was OFFICIAL.

This week I received an email from the TBRC eliminating it as a Long-tailed Jaeger with the following conclusion:
1) length of gonoys too short compared with length of bill basal to gonydal length
2) dark of forehead continuing down well below lores
3) mantle too dark
4) central retrices too short for a bird of this age
5) bird was overall too large
TBRC consensus was that it is a Parasitic Jaeger.

There you have it. It's official. I don't understand some of the above points but it's a Parasitic Jaeger. !

So what's next? Does this get published in some birding magazines? No, the Parasitic Jaeger is a regularly occurring species in the state of Texas and the TBRC will add it to its database of observations but that's that.

Does this mean, our sighting did not make history? We still did, because the Parasitic Jaeger is a first record for Aransas NWR and raises it's species list from 404 to 405. I still have my life bird. Aransas NWF has another species on its list. This remains an incredible birding experience and story.

Dragonflies or Odonata

I have been fascinated with dragonflies ever since a time I was birding at Saul Lake Bog, Kent County, MI in 2002. The meadows were full of dragonflies.

The next morning I was birding from my pontoon boat on the lake and managed to take a couple more dragonfly pictures. I was hooked!

Blue Dasher - Pachydiplax longipennis (Skimmer Family - Libelludidae)


However, it was so difficult that I was not able to take more pictures worth keeping until this summer. I spent two mornings on my pontoon, pushed into the weeds along the shore, and have 5 different species. Dragonflies zigzag back and forth very fast in unpredictable directions. Some sit still for a few minutes but others never seem to rest. Then, since they are really quite small in a photo, you want to be very close the them, but they react to movement by flying farther away. And, of course, they have to pose in the right setting (perch, profile, sunlight, background) for an acceptable picture. (so many requirements, more than with bird photography)

Then, last week I learned a secret from James R Curry's book Dragonflies of Indiana. He captures many of his dragonflies in a net, cools them down to slow their movements, perches them in a suitable setting, and then takes his pictures. Now I know how an other photographer succeeds, but I don't think I will go that far. I'll just run my boat into the weeds and wait.

It is one thing to manage a good photo, now I need to read, identify and learn more about dragonflies. Oh yes, there are damselflies too! (that is another story) It took me five years to identify the next photo and then only with the help of Kurt Mead, author of an excellent little book Dragonflies of the North Woods.

Butterflies

On Sunday, I saw a Common Buckeye Junonia coenia on my New England Asters. It co-operated for me by feeding for more than an hour, so that I could watch and photograph (until I could not edit any more images - over 50). My daughter says I saw one in her insect collection 20 years ago but I have not seen one again, until now. It sure is pretty.

Photo taken at Murray Lake, MI on 9/23/2007All summer I have been taking pictures of butterflies in my garden. The Monarch Danaus plexippus remains a favorite, especially when it poses on my butterfly weed.

Photo taken at Murray Lake, MI on 7/21/2007At Luddington State Park, couple of weekends ago, I saw a Monarch caterpillar on its favorite food, a milkweed plant.
Photo taken at Luddington SP, MI on 9/23/2007 I took the next picture on the Keweenaw Peninsula, in Upper Michigan last summer. I thought I was taking a picture of a Monarch and it wasn't until I was reviewing my photos, that I recognized that it was not a Monarch at all! It was a Viceroy Limenitis archippus which mimics the Monarch. I have never before seen a Viceroy in the field. Notice the black bar across the hind wing on the Viceroy.

Photo taken at Hunter's Point, Copper Harbor, MI on 8/4/2006 I also took some pictures of the Red-spotted Purple Limenitis arthemtis feeding on my Purple cone flower. Again, I did not know what butterfly this was. While reviewing my pictures, I remembered a similar butterfly that I had seen in Texas this spring. When seen from the side as in these 2 photos, the Red-spotted Purple is similar to the Pipevine Swallowtail Battus philenor. Their ranges overlap only along the Gulf states in southern US, but I don't keep range maps in my head (that's why I own books). Now that I have worked with my photos so much, I hope to remember the differences between these butterflies.

Photo taken at Santa Ana NWR, TX on 3/19/2007 I don't know if you have the same problem as I have: that it doesn't matter how many times I have studied the flower, butterfly, or bird in a book, it is not until I have see it live in the field that I can remember its identification marks and recognize it the next time.

Happy butterflying! (Yes, it will become an accepted verb soon!)
