Once the fish leave the elevator they move past the science station and head back out into the river. They also go past a set of observation windows that are popular with the visitors.
me and my family were recently sailing our boat across the ionian sea and we were over 100 miles from the nearest land. suddenly a migrating swallow crossed the stern of the boat and landed on the mid ship. at first it seemed to just land breifly and then fly off but as we watched this angel of the sky fly off we saw it turn back and battle hard against the wind to re-approach the boat and land once again. this was repeated a couple more times before it landed on a seat and closed its eyes as if it wanted to just sleep and rest. clearly it was exhausted form its migration. it then flew inside the boat which is when my sister went down to retreive it. the poor swallow seemed to exhausted to move but seemed also to trust us in a way. pictured here is that very swallow sat happily on my hand before it hoped onto my other sleeping sisters upper body and also went to sleep for what ended up being several hours. it must have soo tired to act like this. we think our boat saved that swallows life as we were so far out at sea when the swallow found us
Their aerodynamic V-formation made me think they were geese. But their straight necks and black feet that do not extend beyond the tail showed that they were swans. The lack of black tipped primary feathers shows that they are not Whooping Cranes. They were flying at high altitude and this was taken at 400 mm. Enlargement shows there to be one Canadian Goose that has joined the swans.
Salvadorans are the 6th largest immigrant group in the United States. Recently, the US has seen a surge in children crossing the border without parents or legal guardians.

Scott Kelby's 4th Annual Worldwide Photo Walk - October 1, 2011
Downtown Baton Rouge, Louisiana
Large flock of Starlings seen here migrating South over the farm fields of Pennsylvania. I took this photo after a hike to a waterfall where I fell in and got my camera wet. It wasn't working properly for a while and I had no autofocus and LCD screen wouldn't work. I was happy I was able to get some of these shots to turn out. After drying the camera off it works fine now :)
Monarch butterflies annually migrate southward each fall. There were 20 to 30 of them in this one spot feeding on a couple of species of asters. What a damn hard butterfly to photograph, as least for me. The don't hold still long and are quick to fly when approached. For more information: en.wikipedia.org/wiki/Monarch_butterfly
No matter how many times you've seen it, raptor migration never gets old. Every fall and spring certain types of birds of prey move up or down the face of the continent in huge swirling flocks that can number in the hundreds of thousands of individuals. Unlike many birds, raptors migrate during the day, when thermals are available. Simply put, thermals are columns of warm air rising into the sky (remember physics? Warm air rises? No? Ok, just smile and nod). The birds circle as they get a free lift up into the sky so that they will stay within the column. When they reach the top they open their wings as widely as possible and glide to the next thermal. In this fashion they spend very little energy as they migrate. Thermals tend to form in some areas better than others-such as the sides of mountains, the interface of water and land, and over ground that is of a darker shade...like soil or asphalt (remember physics again? Dark surfaces absorb more heat and get warm quicker than light surfaces? Still no? Oh well...good thing you're not a hawk). These areas can serve to funnel the birds, and one flock meets another which meets another until there are thousands and thousands of birds. Our most famous raptor migrants are broad-winged and Swainson's Hawks as well as Mississippi Kites like these that are on their way back from a winter in South America. Mississippi Kites will also congregate over burning fields, or those being harvested so that they can harvest their own meals in the form of large grasshoppers. If you have never seen a raptor migration then I strongly suggest that you leave this site right now and find out where the closest hawk watch is to you and when it starts, peaks, and ends. Take it from me, its an experience that is well worth the time, energy, and expense to witness.
Poor thing has a small wound. But she looks happy to have a place to hang out with lots of seeds and shade.

From recent maternity photo shoot in Rundale`s Palace rose gardens.
Weather was tricky - sun, rain, sun rain, but we managed to get needed shots.
This was parked in Cannon Beach, Oregon. The flamingos have probably decorated the car for sometime, because some legs were missing, plus paint was peeling. However, it was an attention getter.
On the hood it said "Take Me". I wasn't tempted.
Some clouds migrating south for the Summer (this is the secret why we get really sunny Summers here in Portugal). 30 minutes compressed into a minute and a half.
Five Weirs Walk, River Don, Sheffield
The River Don was once one of England’s most prolific fisheries, with Atlantic salmon migrating up the river in large numbers to spawn in its headwaters. However, the industries that made Sheffield famous, and the associated pollution that resulted along the Don Valley and the wider Don Catchment, saw a huge decline in all fish species and by the mid-1800s the fish had disappeared from much of the river system. Fortunately the rivers in South Yorkshire are now slowly recovering and in the last 30 years or so there have been major improvements in water quality. Although evidence of the industrial legacy remains, the river and its banks are once again beginning to support an increasing range of plants and animals and water birds have now returned to this stretch of the Don. Mallard are by far the most common, but you may catch a glimpse of a kingfisher, heron or grey wagtail and there have been recent reports of dippers.
Although fish populations have re-established, some physical obstructions remain. Weirs, left over from our industrial activities, prevent fish from migrating upstream and fully exploiting different habitats in the catchment for feeding, rearing and breeding. In particular, the enigmatic salmon cannot return while barriers stop them migrating to their spawning grounds.
Funded by Defra and the Environment Agency, a fish pass has been constructed at Hadfields Weir to enable a range of fish species, among them, dace, chub, salmon, barbel, trout, eels and grayling, to by-pass the weir and swim further up the Don than they have for over 150 years. Acting like a watery staircase, fish and eels are now able to swim or wriggle their way over the weir. In time this will help the fish populations to grow, diversify and become more sustainable.

Migrating crane (?) birds moving south down the Maas River (Meuse). They must use the river to navigate because it runs straight south on this spot.

Day 320 of One Object 365 days Project.
I just watched the sunset- and I saw thousands of little birds fly overhead- songbird migrating- they were flying too high for me to identify them- I couldn't zoom in without loosing the mountains and the sunset..... LOL
today was a perfect Autumn day- clear and warm.
