Winter Begins

img_0108

Frost in the mornings glistening in the sun
Aloe flowers like tongues of flame lighting up the bush
Sunbirds dashing from one flower to the next like iridescent jewels
Woodsmoke in the evenings from bonfires
And spectacular sunrises that slowly banish the mist from the water

What a fantastic time of year along the Garden Route

Fish Eagels Nest Again

At last. We were starting to think this year they weren’t going to nest. It has happened and they are definitely incubating eggs. We don’t know how many but this pair is normally pretty good as raising two or three chicks.

A Beach Scene

On the Southern Cape’s coast we have spectacular diversity: long sweeping sandy beaches, rocky headlands with intriguing rock pools, boulder strewn cliffs and gorges where rivers and forest meet the sea.

If you were walking along a rocky path on a warm day this scene will repeat itself often. It has all the ingredients of a typical  coastal scene; a False Saffron tree (Cassine species) that can withstand salt spray, sun and wind, a Lichen encrusted boulder and a Rock Agamma . The males have a striking breeding display of a magnificent, iridescent blue head which they bob up and down energetically to attract the females.

Another aspect that is typical of our Winter days is be the beautiful clear blue skies.

African Fish Eagles

After last years breeding resulted in two fledged youngsters, we have been watching and waiting to see if their saga continues and indeed on the 23 of May they were seen mating again. They have 3 different nests on our property and we will watch with great interest to see which one they choose to utilize. A sure sign would be when they start carrying green leafy branches to the nest. Most Eagles do this and there are some interesting theories as to why this happens. An obvious answer is to protect and insulate the eggs but it might be more than this. It is possible that trees are used that have a natural insecticide to help keep nest lice out, an example here would be a Eucalyptus species. When we were living in arid areas we would see a few species using Wild Rosemary (Eriocephalus species) for possibly the same reason.

Raptor nests’ are fascinating to watch and because of the bird’s being long lived the nest’s can be immense. I have not measured these nests but examples from other study sites include nest’s that were taller than 6m.

Kranshoek

The Garden Route is fortunately provided with areas of spectacular diversity and beauty. It includes lakes, forests, mountains and within a short drive’s distance a dry country side dominated by succulents. We try and encourage people to get off the main tourist routes and experience the area as we know it. One my favourite areas is Kranshoek.

It is within the Garden Route National Park and provides the spectacular meeting point of Forest and Ocean with the remnant of Gondwanaland’s spectacular break-up. The walk is relatively easy, although sections are steep. Immediately you are struck by the scenery which is dominated by a forested gorge that has been carved out of a cliff face by a small stream.

Except while in the dense Forest, the sound of the ocean is everywhere. It is interspersed with the trilling of the Sunbirds that are attracted to the many flowering Erica species. The plant life is prolific and includes wet forest, fynbos and succulents that grow along the ocean. Another unmissable “plant” is the spectacular orange Lichen on the rocks along the coastal section.

Birding at Rondevlei

Birding at Rondevlei

Rondevlei, where I live, is an estuarine lake on the Garden Route. It is part of a series of lakes that are connected to each other and enter the sea at Wilderness.It is a beautiful area and contribute in a large way to the Garden Routes scenery. Two of the lakes are designated Ramsar sites, which identifies them as areas of international importance to migratory birds. It therefore goes without saying that there is amazing bird-life here, and I try to take advantage of this whenever I can. The Rondevlei has a fantastic hide that is very productive, it doesn’t produce rarities very often but does provide  regular, rewarding birding in a beautiful environment. Common birds seen are African Rail, African Marsh Harrier, African Fish Eagle, Hottentot Teal, Cape Teal, White Backed Duck and depending on the level of the lake, good waders attracted to the mud flats.

One bird that we see quite often has, of late, been prolific. The African(Ethiopian) Snipe. It is a beautiful bird that is not common in many areas and with the Rondevlei being low at the moment, we can see between 5 and 9 different birds feeding together. I recent highlight was for me a maximum count of 15 birds.

At one stage Snipe were popular Game birds(this is where we get words like “sniper”) and so it is wonderful to see aggregations like this, they have a very distinct breeding display that involves Drumming of the wings. There has been no sign of this as yet  so it is possible that they are en route to another breeding site.

Sex,Lies and Deception

Life is strange! In nature in order to survive a species must breed and in order to breed a species must survive! What I find fascinating, as a naturalist, is the endless designs that nature has evolved to solve this conundrum.

Southern Red Bishops are small birds that provide a great local example. They are common, nest communally and don’t appear to be remarkably agile in flight. Easy pickings for a Sparrowhawk, or maybe not .

In order to survive they are incredibly non- descript  and camouflaged.  The difficulty is, being territorial, the males need, at certain times of the year, to see each other and need to be seen by the females. The solution is a quick and timely moult of all that drabness into breeding splendour. The change is quite remarkable and has to be timed perfectly. If they change to early they risk being eaten before mating and if they change back out of the plumage to late they risk not making it to the following breeding season. Survival sits on a very thin line indeed!

Along the Garden Route we have magnificent forests and within these forests are some magnificent trees. White Ironwood (Vepris species) Cape Chestnuts (Calodendrum species) Perdepis (Clausena species) and Knobwoods (Zanthoxylum species) all belong to the Rutaceae  family known to us all from the domestic  citrus trees. This time of the year all of these are being happily munched by the arch survivalists, the insects and by one in particular.

The larva  of the Citrus Swallowtail butterfly has taken the art of deception to a higher level. Referred to as “Orange Dogs” these caterpillars have evolved the strategy of looking just like a bird’s dropping’s, stunning in its simplicity and very effective .

They have solved the survival balance of finding a partner in a more intricate manner , it involves the changing of the physical structure to facilitate the changing needs. Having survived being viewed as a slow moving  tasty morsel they undergo a stunning metamorphosis from a “  bird dropping “  to a  fast moving,  highly visible , regal Adult Citrus Swallowtail butterfly.

Isn’t nature incredible!

Garden Route Fish Eagles Breed Again

fisheaglesbreedagain

It was always our goal to do a Rehabilitation that is sensitive to existing life and adds to the beauty and diversity of the Southern Cape. In 2007 we  moved to Reflections Eco Reserve, a private nature reserve on the Rondevlei lake on the Garden Route in South Africa.

This attractive land was overgrown with dense stands of alien vegetation. Our first priority was the rehabilitation and restoration of the land. In order to do this we decided to clear all the alien pine trees except a line of trees adjacent to the Garden Route National Park. The reason for this was that a pair of African Fish Eagles had been nesting there for many years and great care was taken not to disturb them.

The restoration was successfully in that they bred in August 2008 and two young adults are now being fledged or edged out by their parents. At present we are being treated to marvelous sights and sounds of aerial combat between juveniles and adults including other youngsters from neighboring territories.

Up to eight eagles are seen on any given day making this the prime Garden Route location for Fish Eagle sightings. Other raptors frequently seen here include Martial Eagle, Forest Buzzard, Steppe Buzzard, Black Sparrow Hawk, African Marsh Harrier, Black Shouldered Kite, Peregrine Falcon, Rufous Breasted Sparrow Hawk and Jackal Buzzard.  The level of interaction between these raptors provides precious and spectacular viewing.
