VogelPark - Walsrode Birdpark Hunting for Red-billed HornbillsIn his publication from 2002 Dr. Allan Kemp considers the possibility that at least three of the five or perhaps even six known subspecies of the Red-billed Hornbill (Tockus erythrorhynchus) might better be considered to be independent species (KEMP, 2002). The Walsrode Birdpark has picked up on the discussions on the complicated taxonomy of this species and has initiated a small study on the species status in captivity. Three of the Taxa in question are very new to science. The subspecies Tockus erythrorhynchus kempi from West-Africa was not described until 2000 and Tockus erythrorhynchus ruahae from East-Africa not till two years later. A third form from North-Eastern Africa still remains to be formally described. It has been suggested that these three „new“ subspecies of the Red-billed Hornbill (Tockus erythrorhynchus) are indeed distinctive enough from the 3 other forms, to be considered as a new species (Tockus kempi). Also the subspecies Tockus erythrorhynchus rufirostris and Tockus erythrorhynchus damarensis may warrant status as “good” species. Currently studies into the genetics, distribution, ecology, behaviour and calls of the different forms are ongoing and will hopefully help to clarify our picture of their relationships. Although much of the needed data is still incomplete it does appear that there is some overlapping of the distribution of the different forms in East-Africa where the distribution areas of Tockus kempi ruahae and Tockus erythrorhynchus erythrorhynchus meet in Tanzania. In Southern Africa the distribution areas of Tockus (erythrorhynchus) rufirostris and Tockus (erythrorhynchus) damarensis also meet. Here the dynamics of the two forms hybrid-zones are better understood and studies confirm that hybrid offspring have considerably poorer survival chances in the wild than that of pure offspring from either form (DELPORT, 2004). This certainly suggests that the subspecies are not as closely related as it has been assumed in the past. However until genetic studies confirm these findings and genetic material have been collected from all the different forms much of our knowledge remain speculative. The decades of captive management of Red-billed Hornbills in zoo’s and with private breeders have until now not contributed with much data although importations of live wild-caught Red-billed Hornbills from East Africa often included both subspecies occurring there. In the absence of insight the differences in the birds would frequently be interpreted as sexual dimorphism by dealers leaving numerous mixed pairs in zoos and private holding through out Europe. The VogelPark in Walsrode and the Hornbill Taxon Advisory Group (TAG) of the European Association of Zoo’s and Aquaria (EAZA) are very interested in determining the status of the remaining captive populations.

Maybe , just maybe The Toronto Zoo Board Is In The Middle Of A Financial Crisis And There Is No Place To Go But To City Council like a wayward son go to Mom and Dad for more money...
Although it was made clear by Shelley Carroll (the City's Budget Chief) that the Toronto Zoo has to behave more financially responsible, perhaps the problem is that there is no place else to go. The $250 Million fund-raising plans are a pipe dream (especially after firing the Zoo Foundation), it is not possible to raise admission prices any longer (or face a significant drop in attendance) and the "junkets" (especially to China for the Giant Pandas) by members of the Zoo Board can not be cut significantly for any reason. In other words, there is no place to go but City Council. What a crock! The Toronto Zoo Board needs a reality check, as it has become clear that they do not understand the problems they are facing. Perhaps the thousands of free Zoo passes given to Councillors on the Zoo Board could be cut to zero, perhaps the Zoo Foundation could be re-instated, and perhaps a citizen's advisory committee could be formed to provide much-needed guidance to the existing members of the Board.
This is Proof positive
that citizens should have more direct say in the budget process. Line item veto by a citizen's budget committee might get the desired cuts we must attain. The citizens of Toronto should stand with one voice that we just won't allow a property tax increase this year.

I would be quite interested in any reference you might have to the presence of ethyl mercaptan in carrion. Most literature indicates that dimethyl sulfide and methyl mercaptan are the sulfur containing entities involved. I had also thought that vultures, like many carrion eating and inhabiting species (flies, etc) were attracted to the rather bad smell of the nitrogenous materials (cadaverine, putresceine, etc) produced during decomposition.
Very nice ant exhibit! I wrote a small ant farm post with a reference to your article.

You are a great ambassador for your cousins in the wild, Boomer!
Orangutans are critically endangered because of rapid deforestation and the expansion of palm oil plantations.
If nothing is done to protect orangutans, they could be extinct in just a few years!

What is it with people that want to exterminate venemous snakes? If they weren't an integral part of the food chain and ecosystem, they wouldn't be here! Evolution and natural selection has chosen them as survivors! The fact that they are "harmful" to humans is only a result of humans encroaching on their territories and habitats. Be mindful of your surroundings and situation and you can safely live with the so called "harmful" species that we share this planet with!
Good luck with the event. We have some fabulous wildlife in Devon that's really worth celebrating. We recently had a botanical survey of our small Devon nature reserve, which recorded more than 180 species in about 3.5 acres. And even more amazing was the depth of local knowledge the visiting naturalists had to share - on everything from obscure moths to lichens.

What is sad to me is the lack of common sense regarding venomous snakes that seems to becoming more commonplace.
It has become trendy for government agencies to defend venomous snakes, saying they kill rodents, etc., but non-venomous snakes also kill rodents. I have not heard one logical argument as to what a venomous snake contributes to an ecosystem that a non-venomous snake doesn't.
Any non-biased biologist can affirm species extinction has always happened naturally. It's common sense to kill a venomous snake, rather than let it continue breeding and increase the potential for harm.
The unfortunate consequence of naturalists defending venomous snakes is they make them appear so necessary and harmless that both people and agencies--hospitals, for example--do not expect or prepare for snake encounters.
It's doubtful that many hospitals near the snakes stock the expensive antivenin. Governments should help fund snakebite treatment rather than fund snake protection.
Very cool and novel way to use Skype. Glad to see that people are thinking outside the box with its collaborative application. If it's not too late, you may want to submit this to Skype as a good use of their software for the Skype in business contest they're running.

And don't forget to "Wear Blue and Tell Two"
Another great way to celebrate World Oceans Day is to wear blue in honor of the ocean and tell people two things they likely don't know about the ocean and two ways they can take action. For more Information check out this website:
