Little by little there are fewer birding places left in the province of Cadiz that I haven't visited yet. The marshes of San Fernando were still unknown terrain. Due to a chilly breeze, the weather conditions were far from ideal, especially in the morning.
As soon as I started my walk around Sendero del Carrascón, setting off from a large parking site, I noticed it would be fairly easy to photograph waders up close, provided you carry a tele-photo lens. They were literally everywhere and if you approached them carefully, they were confident enough to allow you to take their picture.
I'd had a quick look at home at the map before commencing this route and thought it was fairly easy to follow the linear track from beginning to end, but soon found out that this area is a true labyrinth. You cannot really get lost, rather disoriented. Fortunately, especially during weekends, there will always be people walking, running or cycling around who know the place well enough in case you manage to get lost.
The most remarkable sight of the morning was certainly a large group of Grey Herons, gathering in one of the canals. Siege is the word used to denote a group of Herons. It seemed as if they were having a friendly chat altogether.
Apart from the Grey Herons, there was a great variety of waders like Redshank, Greenshank or different types of plovers.
Since it was quite effortless to approach the birds, it presented a favorable opportunity to capture portraits of the omnipresent Little Egrets.
The wader birds were focusing on finding food in the mud and not frightened by a discreet photographer. It was big fun to observe a Greenshank plowing through the mud at a minimal distance from the lens.
During my pleasant walk between the marshes I observed thirty different species. One of them was an unexpected Caspian Tern which came flying by at high speed.
Just upon finishing my two-hours-long stroll I heard a bewildered flock of House Sparrows. They were being chased by a male Kestrel but all managed to escape. The Kestrel sat on a pole for a while before returning to the building, preparing another attack.
The House Sparrows of this flock had been more fortunate than the one that I saw hanging in the claws of a Sparrowhawk the day before.
After this quite intensive walk between the marshes, void of mosquitoes thanks to the strong wind and cold temperatures, I still had enough energy to visit another nearby place. In an area called Polvorines, few days earlier there had been sightings of several Wigeons, a species that I still hadn't marked on my life list.
As soon as I arrived I saw a Kestrel, hovering over the military zone right next to the bay that I was about to visit.
When I arrived to the marshes in my second birding spot of the day, I felt tempted to go and descend onto the shore, as the tide was low, thinking that would bring me closer to the birds. In the end it was a wise decision not to do so, as the water was rising quickly and I might have got into trouble.
It was only after walking for an hour or so that I was able to photograph birds from a reasonable distance, when the tide had risen enough to bring them closer to the shore.
In the far distance I also spotted a novelty. I had seen several Great Crested Grebes before, especially at my local patch, Torrox Lagoon, but never had I seen these graceful birds in flight.
Still no sign of the species I was after: the Wigeon. Only a Sandwich Tern showing of its amazing flying and diving skills.
I was on the point of returning back to the car when a fellow birder assured me that he had seen an Osprey a bit further down the track. I decided to take a chance and walked another ten minutes, hoping to catch a glimpse of this magnificent species. I was lucky indeed, there was one, perched on a piece of wood just above the muddy surface of the marshes.
It was impossible to get closer to the bird, but despite the huge distance, my tele-photo did a great job. I knew it would take little time for the tide to submerge the perch, so all I had to do was maneuver myself in a favorable position and wait until the bird would fly off.
After flying a few circles around, a second Osprey appeared and both birds flew in front of a line of wooden posts, occupied by some Cormorants: the perfect moment to take the shot of the day!
Although two more birders that I ran into had spotted a flock of Wigeons, and despite a final effort to go and find them in the complete other end of the bay, almost approaching the Marambay area, I didn't see any trace of them. Better luck next time. Slightly frustrated, I got into the car when a Red-legged Partridge neglectfully walked in front of me. The final photo of the day was one worth remembering!
No Wigeons, but after all a very satisfactory excursion resulting in the sighting of more than 40 different species altogether.

Sendero del Carrascón in San Fernando is a great place to spot and photograph wader birds. Be warned though, this place is a labyrinth and without any preparation you might get lost, especially when you focus on the many birds around you instead of the track. Take a good look at the map, stay on the main tracks, and don't forget your mobile phone, or it could take hours to find the shortest way back.
You will not easily get bored in this area. Apart from the typical wader birds like plovers, Redshank, Greenshank and Greater Flamingo, you are likely to see Herons, Cormorants and an occasional bird of prey.
These marshes attract mosquitoes, so take this into account and bring insect repellent.
More information about Polvorines, San Fernando
Polvorines is an area around a former military base, used in the Spanish Civil War. I had read contradictory opinions on the internet about the possibility to access this area, due to the possible presence of a guard, but during my visit I had no problem at all. I met several people walking down the suggested trail and even saw a group of children with their teacher climbing on one of the old military bunkers.
To get inside the former military zone, in case of the sighting of a non-wader bird, you don't even have to jump any fence. I guess I will not be sued for publishing photos on this page of military installations. In any case, if this is the current state the Spanish Armed Forces are in at the moment, it is bound to happen that the Iberian Peninsula will be invaded soon by any army. I bet even the Vatican would find no trouble fighting its way in.
On the interior of this area, around and behind the old bunkers, you will likely find some passerines, but if you want to spot a whole array of wader birds then put your focus on the muddy area between the water and the old defense walls. You will certainly see hundreds of plovers joined by Whimbrel, Redshank, Greenshank and some Herons.
If you feel in an adventurous mood and decide to descend onto the sand, make sure the tide is not coming in, or you might find yourself a nasty surprise.
You may want to spend some time on the old pier to take good shots of nearby birds.
The two photos below were taken with a difference of two hours, to show how fast the water level rises when the tide comes in.
