Night Heron

I decided to drive down into Kent to see the juvenile Night Heron at Nicholls Quarry near Hythe. I had been thinking about it for a couple of days but had been put off by the fact that the bird was on private property and also that I do not really like twitches. I was surprised then, to arrive at about ten thirty, to find that I had it all to myself and that no one else turned up in the two hours that I watched the bird.

Mind you, they had probably thought about a little more than I had. Its called a Night Heron for a reason. It is active at night and probably best observed at dawn and dusk. During the day it roosts in a suitable low tree or bush and that is exactly what this bird did. I watched its back for nearly two hours as it roosted deep in a bush by the side of the lake.

If I was only a birder I could have walked away happy that I had seen it and that I had my tick, but I am not and I needed a better photograph. The temptation is to step over all the private property signs and go and disturb the bird and if you read SOS that's probably what you expect all photographers to do. The temptation is great, there was no one around to see me but instead I stood for two hours in a pool of frozen mud and water waiting for some movement.

Was I rewarded for my efforts? Well sort of, the heron did stir and preen for a couple of minutes but still with its back to me, then before it settled down again it gave me what seemed to be a begrudging glance over its shoulder.

By this time I was getting cold and I had left my sandwiches in the car so I decided to leave it in peace and move on. It may not be the picture I was looking for but at least I had a record shot of its face and eye or at least part of it.

Out of interest the colours shown on these shots are not what I expected. My memory of the bird is of it being a much deeper brown and of the spots having a green tinge. I am not sure if it's my memory that is letting me down, my eyesight, or my cameras ability to record the colours in the very low light levels within the bush.

Having visited Scotney and Dungeness recently I decided on a change of venue for the afternoon. I decided to drive up to Sheppey and visit Elmley Nature Reserve to view the vast numbers of wildfowl and waders that were in the area. I was not best pleased then, when I arrived at Elmley to find that it was closed. They were demolishing a barn close to the entrance and had decided to close it for the day. I was not alone in my displeasure, I met a number of birders during the afternoon that had also travelled long distances to be there.

Fortunately Sheppey has some other good sites, Capel Fleet, Harty Ferry, Swale NR, Shellness. Too many for me to cover in an afternoon and I got no further than Capel Fleet and the Raptor Point. The wildfowl were a bit distant and I did not see any unusual waders but I did manage to pick up White-fronted Geese.

Sadly everything was too distant to be able to pick out the Pink-footed and Snow Geese that had been reported in the area.

Raptors were plentiful. There were at least six Marsh Harriers flying at the same time. Peregrines, Merlin, Kestrel, Short-eared Owl, Barn Owl, and a probable Ring-tail. A male Hen Harrier had aslo been spotted over at Shellness. The Merlin was picked up by a couple of birders standing next to me but I failed to get onto it yet again. This is turning out to be a bit of a bogey bird for me with the only ones I have ever seen being the two we picked up dead in the road close to Scotney (see blog). 

As usual the only picture that I managed to get was that of a Kestrel

and there was Red-legged Partridge crossing the road as I headed home in the half light

The Night Heron made it a successful day but I had hoped to see a lot more and to get some better picture opportunities around Elmley.

Marsh Harrier

The weather looked good today so I picked Dave up and we headed off to Sheppey in North Kent. Our target was White-fronted Geese which we both needed as a year tick. They had also been reported at Rainham Marshes and Pett Level but with seventy two at Shellness it seemed the best option.

Seventy two and we only needed to see one. I'm sure you have already guessed. No White-fronted Geese at Shellness and in fact virtually no birds at all. Last time I was here it was wall to wall waders, this time all we saw was a couple of Pied Wagtails some Shellducks out on the mud and a few Meadow Pipits. Probably our fault though, the tide was way out and most of the birds with it.

We had a quick look around Elmly Nature Reserve, lots of birds but nothing unusual. There were a lot of geese there but they were a long way off and I only had the bins with me, so no chance of picking out the White-fronted.

It was looking like a disappointing day but we had Oare Marshes as our last stop and it always manages to produce some good picture opportunities.

Shoveler

The Marsh had been flooded by the recent tidal surge and the water level was too high for the waders in the main scrape. Most of the birds were in the waterlogged marsh making the most of a new feeding area.

More Ruff

We also had a squealing Water Rail that came out in the open. Although they are usually skulking in the reeds they are not a shy bird. When their territory is flooded they seem quite happy to come out into the open looking for food and they always seem to be more concerned about Moorhens and other Water Rails than they do about people.

There should be a really nice picture of a Water Rail at this point but I completely blew it, all my pictures were blurred beyond recovery. Much as it pains me you will have to see Dave's blog "Friends of Groyne No 4" if you want to see the Water Rail.

Still a bit of a disappointing day but then as we were thinking of heading home all the birds took to the air as a female Marsh Harrier flew over the site.

An impressive predator

The local crows were not as impressed as I was and were soon in the air to mob it. It's only when you see it alongside the crow that you realise how small it actually is.

It looked so powerful in the pictures above

Evenly matched in the air but the crows have better team work

With the light fading there was just time for a picture of a Lapwing, another of the bird I tend to take for granted. Not only is it one of the best birds to watch in flight but there are very few birds that can match it for colour.

No white-fronted Geese but we had a good days birding and came away with some good pictures.

Cattle Egret

 I think that I will soon have to remove the word "novice" from the descriptor above. I am starting to notice things that even surprise me.

Today I was searching the salt marshes on Sheppey having made yet another failed attempt to get a picture of the Lesser Yellowlegs at Cliffe Pools. There were a few distant Little Egrets and nothing much else but then there was one bird that did not look quite right. I do not carry a scope so my technique is to take a picture on the 700mm set up I use and then to blow it up on the back of the camera to see what I've got. Its not much use on hazy summer days but works quite well as we move into the crisper, clearer winter days.

My initial shot below showed an Egret but the shape looked wrong, the head was too big and rounded and there was no sign of a dark bill.

Blowing up the shot on the back of the camera confirmed a yellow bill but it was clearly not a Great White Egret as it was too small. That only leaves a Cattle Egret. Initially I had my doubts. I would not expect to see it on a salt marsh. It is an insect eater and in this country would normally be seen around cattle.  A  quick check in Collins confirmed the identification ( I hope! ).

 I would have liked a better shot but it was quite mobile and stayed distant so all my shots suffer from being huge crops and over sharpened.

There were lots of other waders on the mud flats but very few that were close enough for a picture.

 There were also a number of Raptors around. Peregrines, Buzzards, Marsh Harrier, etc but the only picture I managed to get was yet another Kestrel.

And finally a few shots of a Wren hunting insects in the fading light.

There is one around here somewhere.

There were plenty of birds around today although they were mostly the usual suspects and very few were close enough for pictures. Still Sheppey is a new area for me and I enjoyed searching out new birding locations. On the way off the island I went past the entrance to Elmley NNR. It was getting late and its a big site to get around so I decided to leave it for another day. Bad mistake. This evening there is a report of nine White-fronted Geese on the reserve and I haven't managed to see one yet this year.

-------------------------------------------------------------------------------------------------------------------------



The identification of the Cattle Egret in this blog was questioned and led to the publishing of a BIRDGUIDES Webzine article, The article and comments are set out below for completeness.

Throughout October and November 2013, a Cattle Egret was reported regularly (although intermittently) from the Isle of Sheppey, in north Kent. The bird, first reported on 3rd October and last seen on 29th November, was generally to be found on the saltmarsh at Harty Ferry, at the south-east end of the island. Despite its being around for several weeks, we received no images directly here at BirdGuides — unusual for such a long-staying scarcity. However, towards the end of last year, Marc Read emailed me a link to Sussex birder Martin Peacock's blog, asking me to have a look at the egret featured in his post from 17th October. On opening it up and looking at the photos of the bird in question — the Harty Ferry bird no less — it was instantly clear that something was wrong. Though labelled as a Cattle Egret, there appeared to be multiple plumage and structural features at odds with that species, although it didn't really seem to fit any of the European or African egret species. I got in touch with Martin to express my thoughts, and he responded with the following:

"The pictures below are of the 'Cattle Egret' seen regularly around Harty Ferry on Sheppey back in October. It was my first Cattle Egret, so I spent some time checking the identification, photographing and learning about the bird. Although I was happy at the time that it could not be anything other than a Cattle Egret, I could not find any pictures on the web that showed examples of black legs and yellow feet as you would find on a Little Egret. The shape of the lower jaw also seemed to be different to the pictures that I was looking at but I put this down to the bird being a juvenile. Finally there was the fact that it was feeding on a saltmarsh along with other Little Egrets, when I would have expected to find it in pastures, feeding around cattle, or in similar habitats.
The shots were published on my blog back in October and I thought nothing more of it. However, since that time I have received queries suggesting that this may be a Little × Cattle Egret hybrid. I have searched the web but although this hybrid is recognised I cannot find any details on what the resulting bird would look like. This is getting a bit beyond my current levels of expertise and I wondered if there is anyone out there that can help me with the identification...
Finally, my apologies for the quality of the pictures. The bird was about quite distant and the pictures are heavily cropped."

So, what is it? For starters, it seems quite clear that this isn't a Cattle Egret. Perhaps the most striking feature is the yellow feet (as in Little Egret), but there are other differences that point away from that as a diagnosis. For example, the bill is comparatively long, thin, and posseses a dark tip, while it also appears rather long-necked for that species. The legs are also rather long and spindly. Could it be an aberrant Little Egret? Personally, I'm not sure: facially, it looks quite Cattle Egret-like with those bright yellowish lores and the predominately yellowish bill (which is perhaps a little shorter than on your average Little Egret). Similarly, the neck, though longer than a typical Cattle, looks quite thickset and rather less 'snaky' than you'd expect in a Little Egret. This, along with the quite plump body and shortish legs, give it quite a dumpy, stunted feel.

Composite showing (left to right) Little Egret, the 'Sheppey egret' and Cattle Egret in similar poses, demonstrating the apparently intermediate structure and appearance of the Sheppey bird. Photos of Little Egret (John Freeman) and Cattle Egret (Tom Victory) from the BirdGuides Iris galleries.

Another species with a yellow bill is Intermediate Egret but, like Cattle Egrets, they have black (not yellow) feet and are larger, longer-necked and more elegant-looking than Little Egrets (not smaller and short-necked as in the Kent bird). White-morph Western Reef Egrets would show paler, greenish legs and a duller bill, as well as a different structure. The bird is also clearly not a Great White Egret.
It is at this point that we mention the 'H' word for the first time. Hybrids between herons, egrets and their allies are rare but certainly not unknown. The Handbook of Avian Hybrids of the World lists Cattle Egret as having hybridised with both Little Blue Heron and Snowy Egret in the USA, and with Little Egret in both Europe and Africa. Furthermore, examples of Cattle Egrets apparently hybridising with Squacco Heron have been recorded in the wild in Spain and Italy (see here and here), while an apparent Cattle Egret × Night Heron has been recorded in captivity in Germany (see here).
Therefore, displaying characteristics seemingly intermediate between Cattle and Little Egret, could the Sheppey bird be a hybrid between the two species? Based on what we can see in Martin's photographs, such an assumption certainly seems reasonable. We'd love to hear your views and opinions on the bird — feel free to leave any comments in the section at the foot of this article!

a lesson for all in checking a rarities true identity. how many people must have seen this and just 'ticked' without thinking. photos show very clearly its not a simple cattle and H seems right

#2 According to Collins....Western Reef Egret (Egretta gularis) can have an all yellow bill, legs greenish grey to black, with yellow toes, clearly it can be cosmetically variable, also size ranges between 55-68cm. (garzetta/Little Egret) 55-65cm. with gularis at the upper range wings can stretch to 112cm as opposed to 106cm for garzetta. Cheers

#3 Well spotted Marc. I wonder how many people saw this and didn't question the ID?
Andy Lawson, 10/01/14 22:23	Report

#4 Hybrid Little x Cattle looks the most likely. It is obviously not a proper Cattle Egret and to be honest I am surprised that it was reported as such for so long.
Steve Lister, 11/01/14 12:55	Report

#5 Why not simply a Little Egret, with an individual fault in the complex mechanisms for controlling the production and accumulation of melanin. Perhaps, with the substitution of a carotenoid-based bill colour?
Colin Selway, 12/01/14 14:23	Report

#6 Perhaps worth remembering that juvenile Little Egrets can look like this http://www.birdguides.com/iris/pictures.asp?v=1&f=365422 Of course this isnt a juv but individual variation can occur, what did these birds look like when they fledged!
Richard Ford, 15/01/14 00:17	Report

#7 On the Western Reef v Little point Ken Murray raised - it should perhaps be noted that the tip of the bird's bill appears to be decurved. Normally regarded as a distinguishing characteristic between these two easily confused species.

#8 A breeding plumaged Cattle Egret was present in North Kent last spring and was seen on Higham Marsh, Cliffe and finally Northward Hill close to a Little Egret colony............
