So that explains the slow dataspeed!

From the #NWO -mailing list: The official report on #birdprotection in #Germany in 2019. For many species the developement continues to be critical. For a few large species some tailor-made measures helped a bit like #WhiteTailedEagle #EagleOwl #BlackStork. Birds in rural areas continuesly under strong press and fast declining, in some areas extincted like #Lapwing #Skylark #GreyPartridge #Yellowhammer #Starling. Also some migratory birds wintering here in strong decline #ForestBeanGoose. Link in german to a press release, in the very bottom the link to the actual report.

A very cool animation short film about exotic bird 🐦 trade. It's very well done. And still humorous.

Homoploide Hybridartbildung?


Offenbar ist es doch möglich! Aus der Kreuzung zweier Arten kann eine neue Spezies entstehen, die eigenständig und erfolgreich ist. Dies haben Forscher im Fall des Kleinen Entensturmvogels dokumentiert. Aus genetischen Untersuchungen geht hervor, dass diese subantarktischen Seevogelart irgendwann einmal aus der Kreuzung des Taubensturmvogels und des Großen Sturmvogels entstanden ist. Offenbar konnten sich diese Hybriden dann zu einer unabhängigen Art entwickeln.

Original paper


Abstract
Speciation through homoploid hybridization (HHS) is considered extremely rare in animals. This is mainly because the establishment of reproductive isolation as a product of hybridization is uncommon. Additionally, many traits are underpinned by polygeny and/or incomplete dominance, where the hybrid phenotype is an additive blend of parental characteristics. Phenotypically intermediate hybrids are usually at a fitness disadvantage compared with parental species and tend to vanish through backcrossing with parental population(s). It is therefore unknown whether the additive nature of hybrid traits in itself could lead successfully to HHS. Using a multi-marker genetic data set and a meta-analysis of diet and morphology, we investigated a potential case of HHS in the prions (Pachyptila spp.), seabirds distinguished by their bills, prey choice, and timing of breeding. Using approximate Bayesian computation, we show that the medium-billed Salvin’s prion (Pachyptila salvini) could be a hybrid between the narrow-billed Antarctic prion (Pachyptila desolata) and broad-billed prion (Pachyptila vittata). Remarkably, P. salvini’s intermediate bill width has given it a feeding advantage with respect to the other Pachyptila species, allowing it to consume a broader range of prey, potentially increasing its fitness. Available metadata showed that P. salvini is also intermediate in breeding phenology and, with no overlap in breeding times, it is effectively reproductively isolated from either parental species through allochrony. These results provide evidence for a case of HHS in nature, and show for the first time that additivity of divergent parental traits alone can lead directly to increased hybrid fitness and reproductive isolation.

Fascinating. Some fish eggs can survive going through a bird's digestive system.
Killifish manage to endure a variety of environments. The wee freshwater fish survive in isolated desert pools, lakes made by flood water, even seasonal ponds that are little more than puddles.

One place scientists didn’t expect to find them was in swan poop. But an international team of researchers reported last week in the journal Ecology that whole killifish eggs make it through the digestive tract of water birds intact, with one egg in the study even hatching more than a month after its transit through a swan. The findings suggest that bird feces may be capable of carrying fish eggs far from their original locations.
[...]
The researchers are planning a similar experiment now that uses eggs from carp, which hatch much faster than killifish. As killifish and carp can be invasive species outside of their normal range, understanding how they spread can help in containment.
