A Lull in the Weather ~ a Stroll in the Park



After a stormy night, the weather cleared a little on Sunday afternoon
so we visited one of our local parks.
There were a few Mallard ducks and Moorhens on one of the main ponds.




This Cormorant had deserted the coast or waterfront in favour of easy pickings. 
There were also quite a few Black-headed gulls. 



The sunshine brought the Grey Squirrels out into the open,
foraging for their buried food supplies.




Suddenly we spotted a small flock of Redwing



These winter migrants breed in northern regions of Europe and Asia,
but arrive in the UK in small flocks.

Speaking of winter migrants, we had read reports of Waxwings in our area,
but we failed to find them.


This white bibbed duck (above) may be a hybrid Mallard,
although when I thought I saw one last time, 
hybrid expert Dave Appleton told me
that he felt the duck I had seen on that occasion 
was 'simply a domestic variant of Mallard,
not a hybrid between a Mallard and any other species.
Domestic Mallards come in a bewildering variety
 of sizes, shapes and plumages.' 

So many thanks to Dave,
whose 'hybrid duck' photos can be viewed here



The Mallard drake above was doing a spot of preening ...


... before setting sail across the pond with his mate.


There was a photographer keeping a close vigil on this corner of the pond,
and if you follow the red arrow above, you will see why.



Every so often a rat would emerge from one hole or another ...
and the one in the photo below took to the water for a swim. 

Members of the public have been asked to refrain
from feeding the ducks in this pond
because the scraps of bread and suchlike
prove particularly attractive to the rat population.

 


Postscript ...

Having checked out the photos on Dave's Domestic Mallard pages here, I'm pretty sure that the bibbed duck above is much the same as the one on his site from South Creake, Norfolk.

Nature Reserves: RSPB Wildlife Garden, Flatford Mill (Constable Country)



We went off in search of some sunshine after a grey cloudy spell, and having checked the forecast carefully, were delighted to find the Stour Estuary around Flatford Mill basking in a glorious summer day. The RSPB Wildlife Garden above was burgeoning with new greenery. Listings on the board included a grass snake in the water, and there was a good show of Orange Tip butterflies in the air.



It was very difficult to photograph the butterflies as they were active and airborne nearly all the time. I managed to get a 'quick pic' of this female Orange Tip as she came to rest momentarily, presumably for some nectaring.
 

You can see the distinctive shadowy markings on the outside of the wing in the photo above. It is only male Orange Tips that have the distinctive amber markings on the inside of the wings.


There were a few ragged Peacock butterflies along the tow-path, and we also saw a couple of Small Tortoiseshells.


This is Flatford Mill (above) ...


... and it is easy to imagine Constable living in this area and drawing inspiration from the scenes that were so familiar to him.

The ducks were flapping about, but we didn't see any ducklings. There was a bit of rivalry between these two!
Another 'Manky Mallard'!

Seasonal Splash: Spring is in the Air (we hope ...)


We have just returned from Salisbury. We didn't have any rain, but there was still a lot of snow banked up on the field edges. It was bitterly cold, but bright at times. The Mallard drake above was heading on downstream in the beautiful clear waters of the River Loddon

I am trying to recall the name of this waterside plant (above) ...

Do drop a line in the comments if you know! It grows in large clumps along the banks of a river or in marshland. 
 It is always a joy at Easter to see a clump of Primroses. This clump was gracing the walls of Old Basing.
What a luxurious des-res above for the Basing ladybirds and mini-beasts! I have yet to see my first Ladybird of 2013, but hope that I will not have to wait too much longer.


Just as we were leaving the site, a familiar shape flew over our heads. I grabbed my camera, and the resulting record shot will show you our first 2013 sighting of a Red Kite. By the time we returned home, we had seen at least one other.



The clump of Coltsfoot above was in Wilton, on the river Wylie. if you know Wilton and Wilton House, you might enjoy Arcadia by Adam Nicolson, which pays tribute to the landscape and its literary figures like Sir Philip Sydney.  
On our journey home, we stopped at Audley End, where I saw what I took to be a hybrid Mallard (above) among the ducks and geese. Dave Appleton tells me that he feels 'it’s simply a domestic variant of Mallard, not a hybrid between a Mallard and any other species. Domestic Mallards come in a bewildering variety of sizes, shapes and plumages.' So many thanks to Dave, whose 'hybrid duck' photos can be viewed here.

It was lovely to see some Tufted Ducks. These are classed Amber in the Conservation Status ranks. The dark duck on the left is a female.
It seems the staining on the swan's head above may be due iron or tannin in the water. Thanks to Martin Aldous for this information, which you can find here. I had assumed it was probably a kind of breeding or adolescent plumage.
 This was a lovely Easter Bank Holiday scene ... though the photo fails to say how chilly it felt!
Not everyone wanted tranquillity, however: this Coot had to hop away from the glare of the Canada Goose! 


Safe landing ...
 ... then time for a snooze.

Beautiful Birds: A Cold Afternoon at Needham Market

A tense moment: Canada Goose meets Mute Swan
A Black-headed Gull surveys the scene.

I'm guessing the huge drake (back right) is a Mallard hybrid

You can read my previous post about hybridisation here.

Time for a spot of ...

... spring-cleaning, aka preening.

The gulls thought so, too.

The one on the left is a juvenile, with paler head, legs and beak.

A final fluff-up ...


... before joining the Mute Swan and other gulls on the water.


The Moorhen preferred to scrabble for food on the bank.
We saw a few distant Fieldfare on the way home.

Beautiful Birds: Egyptian Goose at Ickworth



We noticed an unusual goose in a Suffolk field adjoining the Ickworth Estate. It was a good distance away and the light was poor, but from these record shots I have been able to identify it as an Egyptian Goose (Alopochen aegyptiacus).

Ickworth (taken March 2012)

This species was brought in to Britain to grace the ponds and parks of our estates. A number of these 'ornamental' geese escaped and bred successfully in the wild, particularly in Norfolk.

Egyptian Geese are now considered a feral species, and in this respect I am reminded of the white farmyard-escape ducks that I saw last month at Needham Market. The white (?Pekin) ducks were interacting with Mallards, and I have just read that Egyptian Geese also interbreed - or hybridise - with Mallards.

I am surprised to find that in certain circumstances (or so it seems) ducks and geese pair with one another. Do take a look at the Hybrid Duck page on the Go Birding site for a photo of an Egyptian Goose x Mallard. You might care to look here for as more detailed page on these hybrids.

I am reminded of Nobel Prize-winner, Konrad Lorenz, and his discoveries of imprinting (also a short YouTube here), the way in which a creature - and the duck and goose apparently are particularly good examples - follows the actions of the first other creature it sees after its birth. You may remember the recent TV footage of the Greylag geese flying after their human surrogate ('imprinted') father.

The Egyptian Goose is apparently related to the Shelduck.
