BVA-International: a few numbers and facts

BVA-international celebrates its 27th birthday on November 1th.

Hereby I give you some numbers and facts:

  • Number of articles published in the BVA Magazine till now: 1.130
  • Number of authors contributed till now: 153
  • In 1998 when we founded BVA’s first official technical committee and in 1999 we had our first BVA judges.
  • The first BVA shows was named: Lovebird International. In 2008 we renamed the show to BVA Masters. It was Lieven Vranckaert who came up with this idea.
  • BVA became BVA-International in 2016.
  • BVA-International has for the moment 11 affiliated clubs and societies across the world. There are a few others in the pipeline.

Standaardeisen geupdated

De standaardeisen van Agapornis fischeri, Agapornis personatus en Agapornis lilianae werden aangepast.
De kleurbenaming *turquoise* werd vervangen door de correcte naam Blue1Blue2.

Please share – survey

The genome of the Lovebird is now available. We want to apply for funding to continue the research on Lovebirds but the funding body needs some statistics on whether breeders are even interested in the end products of the research. Please complete the following survey so that we can better understand the specific needs of the breeders.

FAQ: Genetics behind urucum canaries – Urucum kanaries

Unlike wild and domestic canaries (Serinus canaria), the domestic urucum breed of canaries exhibits bright red bills and legs. To identify the causative locus, scientists resequenced the genome of urucum canaries and performed a range of analyses to search for genotype-to-phenotype associations across the genome. They identified a nonsynonymous mutation in the gene BCO2 (beta-carotene oxygenase 2, also known as BCDO2), an enzyme involved in the cleavage and breakdown of full-length carotenoids into short apocarotenoids. Protein structural models and in vitro functional assays indicate that the urucum mutation abrogates the carotenoid cleavage activity of BCO2. Consistent with the predicted loss of carotenoid cleavage activity, urucum canaries had increased levels of full-length carotenoid pigments in bill tissue and a significant reduction in levels of carotenoid cleavage products (apocarotenoids) in retinal tissue compared to other breeds of canaries. They hypothesize that carotenoid-based bare-part coloration might be readily gained, modified, or lost through simple switches in the enzymatic activity or regulation of BCO2.

In tegenstelling tot wilde en gedomesticeerde kanaries (Serinus canaria), of een van de drie dozijn soorten vinken in het geslacht Serinus, vertoont het binnenlandse urucum-ras van kanaries rode snavels en poten.
Om te begrijpen hoe de poot- en snavelkleur bij vogels evolueert en om het verantwoordelijke locus te identificeren, hebben wetenschappers het genoom van urucumkanaries onderzocht. Als mogelijk oorzaak hebben ze een mutatie in het gen BCO2 (beta-caroteen oxygenase 2, ook bekend als BCDO2) geïdentificeerd. Dit is een enzym dat betrokken is bij de splitsing en afbraak van carotenoïden van volledige lengte tot korte apocarotenoïden. Testen geven aan dat de urucummutatie de carotenoïde splitsingsactiviteit van BCO2 tenietdoet. Consistent met het voorspelde verlies van carotenoïde splijtactiviteit, hadden urucumkanaries verhoogde niveaus van carotenoïde pigmenten. Ze veronderstellen dat carotenoïde-gebaseerde kleuring gemakkelijk kan worden verkregen, gemodificeerd of verloren kan gaan door eenvoudige schakelaars in de enzymatische activiteit of regulatie van BCO2.

Cursus agaporniden 2020

Dat er heel wat belangstelling is voor de cursus agaporniden is een feit. De eerste cursus werd in 1999 in Kalken georganiseerd en was toen gespreid over 10 zaterdagnamiddagen. Sindsdien werd om de twee à drie jaar deze cursus opnieuw georganiseerd. Omdat er heel wat deelnemers uit Nederland kwamen, werd vanaf de vierde cursusreeks in 2006, de cursus gespreid over 5 volledige dagen. In 2020 zijn we toe aan onze jubileum uitgave, want dan gaat de cursus voor de 10de keer door.

De Pluim 2019

Er werden dit jaar een aantal liefhebbers genomineerd voor De Pluim. Een nominatie sprong er voor ons uit en dat was de nominatie van Edwin Vloeberghen.
Heel wat mensen spraken hun waardering uit voor de inspanningen die Edwin de afgelopen jaren getroost heeft om het genus Forpus in de aandacht te brengen.

Mitochondrial genome of A. fischeri

Recently, Chinees scientists, described the complete mitochondrial genome of A. fischeri. Its mitochondrial genome is a circular molecule of 16,719 bp in size, and all genes exhibit the typical gene arrangement according with most avian consensus. The genome information obtained here could contribute to the conservation and utilization of A. fischeri.

Everyone knows by now that in recent years there has been a lot of talk about blue birds within the genus Agapornis. For starters, we are now certain about the existence of blue 2 in Agapornis fischeri, there is the possibility of several new mutations and a breeder in Spain has bred green young from a pair of blue Agapornis personatus. It goes without saying that a lot of people are left with questions. A lot of the questions we currently get are about this topic and the internet and social media is buzzing with rumour, gossip, theories and speculation. Each person has his own opinion. Hence it is difficult to get a clear view on the matter.

Can parrots synthesize phaeomelanin in feathers?

Can parrots synthesize phaeomelanin in feathers? That is a question that is regularly asked among aviculturists and not seldom causes long discussions. Unfortunately, as we already mentioned several times, there is no correct answer on this question.

Till now, we have not heard of any scientific study that confirms the presence of phaeomelanin in the feathers of parrots. There is one recent paper that mentions phaeomelanin in parrots: https://besjournals.onlinelibrary.wiley.com/…/1365-2435.127….

The authors seem to assume that phaeomelanin is responsible for some plumage colours of parrots together with eumelanin, carotenoids and psittacofulvins, but they did not conduct any chemical analyses to confirm that (and we know now for sure that parrots only have psittacofulvins in their feathers and no carotenoids). They cite some studies that investigate the chemical nature of feather pigments, but among those cited studies, we cannot find any confirming the presence of phaeomelanin in parrot feathers.

In MUTAVI, we examined several mutations in Psittaciformes by cross sections and never found phaeomelanine in the feathers. We never said it is impossible, but till now there is no scientific evidence that parrots produce phaeomelanin for pigmentation. Some scholars think it has an evolutionary reason.

The best way to investigate this is by Raman spectroscopy. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. So a perfect method to identify phaeomelanin in feathers.

Since it never has been investigated, it is be a good point to test. We can not do it, but I contacted several researchers and we found a scientist who is willing to help us.

Of course we need to pay for the analyses, but I think it is worth the money. Hopefully this research can give us a clear answer.

I heard from several breeders that they believe they have examples of parrot species / mutations that have phaeomelanin in the feathers. So now it is the time to step forward and we will try to find out the truth.

We will collect feathers from these species and we will analyse them.
We hope to collect samples from species from the three super families in Psittaciformes: Psittacoidea, Cacatuoidea, and Strigopoidea.

Who is willing to help, and can provide us feathers of these species before the end of this month?

For the sake of a good order: we don’t know how long it will take before we will have some results. So please be patient. ?
