The fossil record of the Anhingidae is rather dense, but very apomorphic already and appears to be lacking its base. The other families placed in the Phalacrocoraciformes sequentially appear throughout the Eocene, the most distinct – frigatebirds – being known since almost 50 Ma (million years ago) and probably of Paleocene origin. With fossil gannets being known since the mid-Eocene (c. 40 Ma) and fossil cormorants appearing soon thereafter, the origin of the darters as a distinct lineage was presumably around 50-40 Ma, maybe a bit earlier.
Fossil Anhingidae are known since the Early Miocene; a number of prehistoric darters similar to those still alive have been described, as well as some more distinct genera now extinct. The diversity was highest in South America, and thus it is likely that the family originated there. Some of the genera which ultimately became extinct were very large, and a tendency to become flightless has been noted in prehistoric darters. Their distinctness has been doubted, but this was due to the supposed "Anhinga" fraileyi being rather similar to Macranhinga, rather than due to them resembling the living species
Common Darter....Sympetrum striolatum.

Passing Bedrove shops is Arriva The Shires (KE53NFG 3829) working Service Pink Route 8 to Aylesbury bus station & is seen proudly wearing the new Arriva corporate livery being the first dart to recieve this new colour. New to the Shires fleet in 2003.
I went to a small wetlands area yesterday and saw quite a few of these.
I struggle to identify them as even Common Darters seem to come in a variety of colours.
Any idea what this one is ?
The River Dart near its source on Dartmoor, still more of a babbling brook than the mighty river it will become before it meets the sea at Dartmouth.
Just an assortment of darter species that I've photographed, all from Indiana except E. exile which was in Michigan.
Old Lodge Nature Reserve, Ashdown Forest - a trip to see if these were around. I had just 2 sightings by the pond, and 1 flying over the heather, there could have been more, but they are so small and well camouflaged they are easily missed.
Australian Darter (I think) drying its feathers while hiding in the reeds at Colleges Crossing, Brisbane River near Ipswich.
Apologies once again to my flickr friends for my absence in recent and coming days. I will try to keep up but not the best right now.
Take care all and keep flickring.
Here's the gen -
Little scene from the streets of London. Kept it because of the elegance of the lady and the harmonic colors. I like color street photography!
Still quite a few Common Darters around the local area, be interesting to see if they last into November
While I was waiting for some Kayakers to do their stuff - I noticed this and the camera club does have a reflections comp coming shortly, though I probably have better than this.
I did the same hike/tramp but in reverse in 1979. This is Dart Glacier in February of that year. It has changed a bit.
Mt Aspiring National Park, New Zealand
Sympetrum striolatum ♂
We put the wooden sunbed away for the winter last night so he will have to find another perch.
Dart SLFs have been around longer than you think. One leaves Aberllefenni, deep in rural mid-Wales in April 2000. Relics of the local slate quarrying industry are visible. Arriva certainly doesn't run here now!

Ruddy darter (I think) dragonfly at rest on grass flower. There's also a tiny spider hiding in the grass.
Anhinga female Florida.
Blue eye shadow means mating season. Anhingas develop this bright blue around the eyes when they are in mating season.
The anhinga (/ænˈhɪŋɡə/; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word anhinga comes from the Brazilian Tupi language and means devil bird or snake bird. When swimming the origin of the name snakebird is apparent: only the colored neck appears above water so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.
The anhinga is placed in the darter family, Anhingidae, and is closely related to Indian (Anhinga melanogaster), African (A. rufa), and Australian (A. novaehollandiae) darters. Like other darters, the anhinga hunts by spearing fishes and other small prey using its sharp, slender beak. (Copied from Wikipedia)
