Super Mum does it again

Snowdrop has laid eggs in the same spot for the last 6 or 7 years...

With so many baby birds growing up around the centre at this time, we thought you may like to know that our 'Supermum' Snowy Owl, Snowdrop, is once again sitting on a clutch of six eggs. To date, this formidable matriach has managed to hatch well over 30 chicks here it Stonham - it seems that the chilly winds of the Mid Suffolk flatlands are to her liking!

Last year Snowdrop raised five babies, with only one egg of the clutch failing to hatch as it proved infertile. Infertility is something that happens on a regular basis with breeding birds of prey and we can determine whether an egg is fertile or not by a process called 'Candling'. This means holding the egg close to a light source such as a torch or (as in medieval times) a candle, which enables you to see ‘through’ the egg - if you can see an embryo developing inside, this is confirmation that there is a chick growing inside.

Snowdrop will be sitting on her ‘scrape’ - the rudimentary nest she scrapes from the ground in her aviary - for approx four weeks. A day or so before the eggs are due to hatch we will take them from the scrape, label them carefully and place them in an incubator, where they will hatch in the order that she has layed them, each usually a day or two apart.

(We do this because Snowdrop has a condition called haemoproteus, which is a form of bird malaria. It is a condition passed from bird to bird via the saliva, so in order to protect the clutch we have to prevent the mother feeding the young - which is why we remove them to the incubator for the last stages of hatching.)

Once hatched the chicks remain in the incubator for a few days, at which point we begin a process called 'imprinting': contrary to popular perception, owls have relatively small brains and so, as the falconers begin to feed the youngsters by hand, they take on the guise of ‘mum’ and so are ‘imprinted’ to the human form as the food source and, if you like, ‘next of kin’. We will keep you posted as to the progress of the chick.

Snowy owls come from extremely cold climates and can withstand extraordinarily inclement weather conditions - such as you might find in the Arctic Tundra, where temperatures can drop to -40ºC - which other birds find intolerable. Snowies nest on small outcrops of grassy tussock and blend in perfectly with the surrounding area. The female is always larger of the sexes and has more black speckling on her back, which helps her camouflage herself and her nest from predators.

Snowy Owls are diurnal hunters, which means they hunt their prey at sunrise and sunset. They like to hunt from perches, adopting a sit-and-wait routine, feeding on most ground dwelling mammals such as lemmings and voles.

Although not frequent visitors to the UK, a few pairs have nested on the island of Fetlar, in the Shetlands.


More new arrivals...

This week S.O.S warmly welcomed Tiny, our new male Burrowing Owl, to the Sanctuary.

Tiny has been brought in as a long-awaited companion for Titch, our female Burrowing Owl, who has been with us since early last year (for more information on Titch, click here). Raised locally by a private breeder, young Tiny is Suffolk born and bred and comes from the same home as Titch and also Baloo, our Indian Eagle Owl. In our efforts to provided the best surrounding for the owls in our charge, wherever possible we like to keep them in pairs and so we hope that Tiny and Titch prove to be a perfect pairing!

The Burrowing Owl is a small owl with with a round face, no ear tufts and what look like disproportionately long legs. It is a species normally found across north and south America and whose favourite habitat is open landscapes and deserts with areas with low vegetation, where they roost in burrows. Though often active during the day, Burrowing Owls do most of their hunting between dusk until dawn, feeding on a wide variety of prey and changing food habits according to location and time of year. Beetles and grasshoppers form a large part of their diet, supplemented by small mammals like mice, rats, gophers, and ground squirrels. Burrowing Owl live up to 9 years in the wild.

Following on from our previous blog about some of the other new arrivals at Stonham this Spring (see "New Arrivals" and "First Lady, Second Generation") we’ve now come up with a suitable name for one of our baby European Eagle Owls. We thought it best to call at least one by a name that was linked to his mother's, and as Rheia is the name of a Greek goddess, our choice is Hades because, as you can see from the accompanying pictures, he is indeed one hell of an owlet!

Hades looks like a bundle of fun now - but his sheer size as a youngster and strong talons illustrate that he will soon be a quantity to be reckoned with!

Now with a few weeks under his belt, along with our new Malaysian Wood Owl Bali, Hades has moved from his first home - the rudimentary but well protected floor of our falconer's hut, where they have both spent the last 5 weeks happily crashing into everything in their path - into a crèche aviary.

This provides a secure space for young owls to stay during the day, where they can adapt to the outside world, the climate and the enquiring scrutiny of visitors at S.O.S; and also stretch their wings and fledge as they grow their all-important flight feathers through. At night, whilst the evenings are still chilly, they are brought back indoors but once old enough, they will take up residence in their own full size aviaries at S.O.S!

As always, we'll keep you posted on their progress.

New Arrivals at S.O.S.

Spring has now well and truly sprung at Suffolk Owl Sanctuary this week with the arrivals of our first babies of the year.

This morning, whilst one of our falconers was doing his routine daily check on our expectant mums, we discovered that the stork had already delivered to some of our birds! Phoenix and Huron, our resident Great Horned Owls, are now the proud parents of two chicks; Meluka our Malaysian Wood Owl has one chick; and Dewhurst and Forrest - a pair of Harris Hawks - also have one new arrival.

So now is a good time to for a word in general about the breeding season ahead for wild owls and other birds of prey, as you too may be in for some surprises if you're out and about in the countryside. One of our main objectives as a charity is to protect, care and tend to wild owls and other birds of prey that may be injured. During the breeding season we get quite busy in our hospital due to members of the public bringing in young owl Tawny and sometimes Barn Owl chicks that they may have found along hedgerows or by the side of the road. Each type of youngster should normally, however, be treated differently.

Baby Tawnies found in this way are often what are known as “branchers”. This is because they very often have fallen from the branch during an exploratory excursion from the nest. But in most cases, never fear: the parents will usually be keeping a watchful eye on the youngster whilst hidden safely above and will normally help its offspring back to the nest by encouraging it to scrabble back up into the tree. So unless the bird is obviously injured or abandoned, it is probably better left where you found it, rather than putting it through the stress of a journey to us, and eventual return to the wild.

However if a Barn Owl chick falls from the nest then it is likely to be left unattended as Barn Owls tend to leave their young if they fall. So if you spot a Baby Barn Owl on the floor, then help is needed - call your local vet or us for advice on what to do. Click here for further information on orphaned & injured owls.

Chipmunks ahoy!

Finally, back on the breeding front, we were also surprised to find 8 new baby chipmunks in our enclosure over the weekend, as Dean and Matt went to move them into their new, newly completed home. They are really cute - why not come along and pay them a visit soon? We look forward to seeing you.

A Vet in the Hand...

If you are a long-time supporter of our work at S.O.S, then you will be aware that our main area of concern is the care, rescue and rehabilitation of injured wild owls and other raptors from around the region.

But you have recently joined the ranks, hopefully this particular Blog story will give you some idea of the specialised work we do, often - but not always - with a successful outcome.

Throughout the course of the year we have many injured wild Owls and other birds of prey brought in to us for inspection, usually by concerned members of the general public. For the most part we are able to treat the birds ourselves in our purpose-built Raptor Hospital, a facility which was recently fully refurbished thanks the funding of your generous donations.

When an injured bird arrives at the centre, we firstly enter the details of the circumstances & conditions of the creature into our register before giving them a quick physical assessment, looking for obvious signs of external damage. Then we check for bone fractures, concussion and other aliments, relying on our accumulated experience of identifying minor injuries that have crossed our path over the years.

But whilst we are able to deal with many of these instances, we also receive many cases which require the attentions of a higher authority in avian medicine - the veterinarian.

Such was the case this week, when we were brought a Tawny Owl which arrived in a very poor state indeed. We could see immediately that this particular individual had a badly broken wing, probably - as the bird was picked up by the road-side - the result of a collision with a vehicle of some sort. The unfortunate bird also had signs of a condition called 'frounce', which swells the throat and makes it hard for them to swallow.

Without hesitation, we decided to take the casualty straight to out local veterinary practice, the Stowe Veterinary Group in Stowmarket, who are always willing to give us first rate & usually preferential assistance when it comes to wild raptor care. Here, vet Bill Besley confirmed our suspicions on both counts. Of particular concern was the frounce, or Trichomoniasis to give it its proper name, because - as it can make feeding difficult - it can compromise the birds natural ability to heal itself. The disease is increasingly prevalent pigeon and dove populations and it seems likely that this particular Tawny Owl picked it up by injesting an infected bird of this type.

It is possible to treat frounce if caught in the early stages but the course of care is fairly intensive and drawn out, including medication twice daily and hydration by crop tube every hour, which can cause no small degree of distress and discomfort. Unfortunately, for this particular Owl the prognosis was not good, and in the end the vet recommended it would be kinder to end its suffering than make it endure a very long recovery period with no guarantee of a successful return to the wild or a worthwhile quality of life.

So - win some, lose some. Next time, hopefully we will be luckier.
