United States Navy Grumman E-1B Tracer
Bu.Aer No.148908p/AU775 with Airborne Early Warning Squadron VAW-121 aboard the Aircraft Carrier CVSG-56 USS Intrepid during her visit to the Royal Naval Dockyard at Portsmouth way back in September 1971.
The forerunner to the current AEW Grumman E-2 Hawkeye and based on a modified S-2 Tracker airframe the Tracer was a strangely configured aeroplane with a different tailplane layout and that huge radome mounted above the fuselage. No doubt with it's aerodynamic fairing, extra lift was gained but it still looked somewhat incongruous - especially when with everything stowed as here.

I believe this posing bird to be a female Anna's Hummingbird. The bill is straight, and the other markings are a good match for the field-guide images. However, I later noted several "females" to have traces of gorget color... implying that they are juvenile males. (If you can more confidently ID this lady -- or any of my photo birds -- please comment; I've learned to be humble especially in selected ID areas like this one for female or juvenile Hummers!)

I had a wonderful shoot with a fusion folk jazz artist called Trace Homles on friday. I done a collections of images but i thought this one stands out from the forest session we did. There is one cracking image from the sunset session we did a hour or so later. You'll get to see that soon. These images were done for her new website. Trace is is in the southern national final for live and unsigned . This is why she needed me services for images :-)
Hope you all like?

Trace a line in the ground and dig it in,
Leave the line abandoned for 70 years,
Then go back and follow the line,
A wall of green stands in between.
Nature prevails!

This may look like a petroglyph or a piece of carved pottery, but it is fossil. This fossil is not an animal; it is a burrow made by an animal. Burrows, trails, feeding, and resting traces are all called trace fossils or in German Lebensspüren (traces of life).
The study of trace fossils is called ichnology and ichnology can tell us a great deal about the sedimentary environment in which the trace fossils were formed.
This specimen (PE 52482) Heminthoidea, is a Cretaceous (145 to 66 million years ago) feeding trace probably made by a worm.
Dr. Dolf Seilacher, a German paleontologist who pioneered the study of trace fossils, studied the different types of trace fossils that occur together and recognized several different sets of reoccurring trace fossil assemblages that he called ichnofacies. These different ichnofacies formed in different environments and Seilacher studied and identified the different environments in which the ichnofacies formed. The Skolithos ichnofacies indicates a high-energy, shallow-water environment and is made up of mostly vertical tubes or burrows. The Cruziana ichnofacies is an environment below the normal wave base that is rich in nutrients and has a high diversity of trails and burrows that crisscross each other. A feeding trace, like the Heminthoidea specimen pictured, that has a regular pattern of looping horizontal burrows close to the sediment surface which never branch or cross each other, are from the Nereites ichnofacies which is a deep water environment with very little nutrients. Traces similar to Heminthoidea have been seen on the modern ocean floor at depths of over 4,000 meters (13,100 feet).
Trace fossils not only tell us about the environment they also can also tell us about the behavior of the animal that made them. In this case we see that the animal had a very efficient feeding pattern that never crossed sediment it had already processed. Computer programs made with simple rules have been used to model this behavior and understand how this type of behavior evolved.
Dolf Seilacher died April 26, 2014. He was a pioneer in studying trace fossils, and also made important contributions in many areas of paleontology including, constructional morphology, Lagerstatten, and taphonomy. He recorded his contributions to science in over 200 publications.
Dr. Seilacher is also featured in the Imax movie "Volcanoes of the Deep Sea" where he dives 3,500 meters (11,500 feet) to the ocean floor in a deep sea submersible to try and discover the identity of the animal that makes the strange hexagonal trace called Paleodictyon nodosum that is found in modern deep sea sediments and as fossils dating back 50 million years to the Eocene.
