Bird Books for Sale

 

Good day,

I’m sending this to the chairs of all clubs associated with BLSA. Would any of your members would be interested in any of the books in the attached list, from Peter Barnwell? He is a photographer and film-maker living in Bethulie in the southern Free State and who plans to sell his house and buy a caravan to tour around the Kalahari and Namibia. He has a large library (mostly bird and other natural history books) which he has decided he must reduce drastically and is offering them for sale. Most are immaculate condition – some have never been opened! Anybody interested in looking at further lists, please contact me.

Kind regards,

Brian Colahan    colahanbrian@gmail.com

Anyone wishing to purchase books should contact Peter Barnwell directly at the email address supplied with the list of books available below;

Restocking the Heronry at Vermont Pan

 

This morning six volunteers carried out reconstruction work at Vermont Pan.  The heronry – which is now occupied by White-breasted Cormorants and Egyptian Geese – was looking a bit bare in patches, so we added a few loads of branches to give the birds new roosting and nesting sites.

Present in our group was Gavin Turner, the designer of the structure and he reminded us of how, when the original structure was built, they got it wrong, by making a mirror image of what had been prefabricated in Mike MacNaught’s garden.  Today the whole thing smells pretty awful, being covered in guano, but there were plenty of nests and even one Egyptian Goose nest with nine pretty eggs waiting to be hatched.

Carrying the branches out into the pan was a messy business, squelching through deep sucking mud, but we got the job done.  Everybody certainly needed a good bath afterwards!  Let’s hope the birds appreciate our work.

Volunteers required to re-build the Heronry at Vermont Pan

 

We are looking for volunteers to help restock the Heronry on the Vermont Salt Pan.

If you are free for about two hours this coming Thursday the 13th June at 09.00 at the Car Park in RockHopper (second right down from the Onrus Trading Post traffic lights).

The sticks and branches are there ready and waiting.

We plan to take them out to the Heronry to build it up before the nesting season commences.

If you have the time and are willing to help, please contact me ASAP either by phone or by email for more information.

Your help will be sincerely appreciated.

The club needs to transport a load of branches from Kwaaiwater to the Heronry at Vermont next week and also to collect around 20 stacking chairs from Somerset West.  If anyone has a bakkie and is willing to assist, please call John Saunders at 028 316 2302,  or mail him at  antares@hermanus.co.za  Thank you!

Name Badges

In order to improve our getting to know each other in the club, we will in future be wearing name badges at all club meetings.  Some of you already have badges, but there are many who don’t.  In order to know which new names need badges, will all members who already have name tags, please let Sue know asap.  Her email address is francks@intekom.co.za

 

Fynbos Fires and their Consequences for Birds

 

Positive benefits of fynbos fires are short-term food opportunities for some species

Raptors are often attracted to fire and its charred results, moving in from adjacent habitats. This is particularly evident where predatory birds may flush out injured birds and animals or find other carrion. Jackal Buzzards, Steppe Buzzards and Spotted Eagle Owls are known to visit burnt areas immediately after smoke dissipates. After a relatively short time they move on.

Other species which may take advantage of the aftermath of fynbos fires

The Fork Tailed Drongo, Fiscal Flycatcher, Fiscal Shrike and Cape Grassbird are known to take up the debris of insects, arthropods and the seeds of various plants such as P. falcifolia and L. eucalyptifolium which are exposed about 2 weeks post fire.

Genetic Diversity 

Nectivores such as the Cape Sugarbird, Orange Breasted Sunbird and Cape Bulbul will immediately move away to neighbouring areas, however, this may be advantageous to genetic diversity as they colonise with other groups, returning only once the area has recovered. They are significant pollinators, playing a vital role in continuing fynbos survival.

Negatives are longer-term!!!!!

Fynbos Recovery Periods or seasons required for the fynbos habitat to recover vary. Usually, fire patterns are such that most fynbos bird species are able to simply re-locate temporarily to unaffected areas of similar habitat, at least until the affected areas recover. Some fynbos species take longer to recover, hence food sources can be limited. Neighbouring suburban gardens often become a refuge for the nectivores immediately post fire.

Frequency of fire impacts on the recovery of certain fynbos plant species, which in turn impacts on suitable nesting sites, for example the upper branches of  Protea Neriifolia, preferred by the Orange Breasted Sunbird. This  plant species is slow maturing, taking about 6 years to reach maturity, and produce fruit. If the fruit is burnt before ripening, no seeds will be dispersed! Densely concentrated growth of Leucodendron salignum indicates where an area has been burnt too frequently, compromising non-sprouting fynbos species, thus minimising preferred nesting habitats for some fynbos bird species.

The intensity of fires can significantly alter the fynbos profile of an area. Whilst some plant species may benefit from low intensity fire heat to allow for seed dispersal, other plant species can be eliminated by hi intensity fire. Total destruction of the underground parts of the plant and buried seeds can occur. Again, this impacts on breeding, nesting and the food source of endemic birds and may also lead to fragmentation of breeding sites.

Breeding season versus Fire season.

At the moment, most fires occur during hot Summer and Autumn months, when breeding is finished. Most fynbos birds breed during late Winter and early Spring, so impact on breeding is generally confined to loss of suitable nesting sites. However, if fires occur earlier in the breeding season, fynbos bird species most affected would be those nesting in fynbos scrub, such as Cape Grassbird, Karoo Prinia, Orange-breasted Sunbird, Neddicky, Grey-backed Cisticola and Cape Sugarbird. Some such as the Victorin’s Warblers concentrate  into damp, south-facing stream-side kloofs, shielded from all but the fiercest fires.

Season’s Greetings

il_fullxfull.1097075526_9n8s

The Hermanus Bird Club wishes all its members and readers a very happy and blessed holiday.  If you are on the road, travel safely and enjoy your time with friends and family.

Remember to keep your eyes peeled for those special birds which may occur in your area.

We look forward to seeing you again in 2019 and hope that somebody with some minimal accounting skills will step forward and take on the position of Club Treasurer. This is a serious request, as the club will be without a Treasurer next year.  Come on – do your bit for the HBC!!
