Last September I noticed a Kingfisher on my local brook which is in fact a flood relief drain that runs through the edge of the city. I managed a few photos at the time and hatched a plan to get some better ones. I built a very rudimentary hide on the edge of the brook and down the bank. I used a camouflage tarpaulin and 4 hardwood tree supports from a garden centre. I draped the tarp over the posts and secured it with cable ties. I then trimmed of the excess material and of course left one side unattached so that I could get in and out. It is around the size of a Punch and Judy tent but not as tall. It is tucked very tight to the side of the bank which is around 5 foot high so the hide does not protrude higher than the bank and is therefore a bit hidden. In time, plants such as dock, Himalayan  Balsam, Reeds and the like have grown around it making it even more hidden. I use a small shooting stick chair which I bought from a charity shop. This is left in place and so far after 9 months it has remained untouched. It is part of the landscape now and birds perch on it constantly, including Kingfishers. I obviously needed to cut  holes in to the fabric to poke the lens through. These holes are on three sides so I can focus out depending on the time of day and ambient light. It's pointless shooting in to the sun as I am sure you know. Then with my shooting stick chair, I just position myself in the right direction.   To encourage Kingfishers to the right area you need to know that Kingfishers are firstly very territorial so if you see one then you know you will eventually see it again, if of course, the habitat is suitable.  They need to eat their own weight in fish every day come rain or shine, summer winter, snow and ice and driving wind. Their own weight is around 15 minnow size fish. Position some attractive perches around the hide. There are no trees on my brook so it makes it easier to attract a bird to you by removing all the other good perches and putting them near to you. Kingfishers are light enough to perch on Dock stems and reeds which they use to fish from, however when it comes to dealing with prey they need a hard, usually wooden surface.  This is where you benefit and are able to manipulate your Kingfisher. Appreciating this facet of the KFs behaviour is crucial. I have seen one of my KF's fly at least 500 yards with a fish back to my hide, because he knew that here was a solid surface to beat his prey to death. In my experience, make sure that there is some of the perch  over dry land.  Kingfishers I have watched  always perch over this dry land to deal with their prey because when they drop it, which happens often, they are not going to lose it back in the water…….clever things these Kingfishers.  Winter is easier to get good views. Days are shorter and the KF needs to feed in the morning and then late afternoon. Obviously with shorter days this means they spend a proportionally greater part of the daylight fishing. As I have said, if you have conditioned your  bird to know about the ideal place in front of your hide, you have cracked it!  Also you need to be mindful of the law and do not photograph if you see two birds together, they MUST be breeding.  In that event,  because two Kingfishers will never be together unless they are paired up or it's an adult and youngster. In either event, without a license you are breaking the law to photograph at a nest site.  A KF's territory is big and for days , even weeks he/she may have found a better place for fishing far from your hide. Given time though, he will return, or if he has departed the territory he will be replaced by another bird eventually. In the meantime enjoy the other birds that will take your hide as a part of their territory too.  From my hide in the last year I have photographed Jack Snipe, Snipe, Grey Wagtail, Wren, Pied Wagtail, Little Egret, Grey Heron, Meadow Pipit, Teal, Mallard, Moorhen, various gulls, Blackbirds, Sparrows, Greenfinch and Goldfinch all, like I said in the city. In fact 100 yards from the local Lidls!!!
