Javan Green Magpie (Short-tailed Magpie)

Let me introduce you to the Javan Green Magpie, also known as the the Short-tailed Magpie or Cissa Thalassina.

CorvidCorner did not take this photograph. If you are the photographer please let us know and we will add your name immediately. Thanks!

Striking bird, eh? The Javan Green Magpie is part of the Corvidae family. This beautiful bird is endemic to the mountain forests on the Southeast Asian islands of Borneo and Java. Yep, those are the only two places you can find the Javan Green Magpie. It lives in thick vegetation in the upper and middle levels of forests and makes only short flights.

The Bornean subspecies jeffreyi has whitish eyes. The nominate subspecies from Java, as well as other members of the genus (Cissa), have dark reddish-brown eyes. The Javan Green Magpie is considered critically endangered with a population of about 50 to 249 mature individuals.1 ” It has also been suggested that the total population probably does not exceed 100 individuals and could number fewer than 50 individuals, as there may be only one or two dozen birds at each of up to four sites where the species was recorded from 2001 to 2011 and may still be extant (van Balen et al. 2011).”2 These birds are endangered because of habitat loss and habitat degradation driven primarily by agricultural expansion, logging and mining. Unfortunately, they are also often trapped in cages set out for the cage-bird trade business. =( Only a small number have ever been recorded in bird markets which indicates they are caught but then killed because they are not necessary.3

As you can see from the photograph above, the Javan Green Magpie mostly eats invertebrates and small vertebrate prey as well as berries (I saw a photograph of one with a berry in its mouth).  Breeding appears to take place throughout the year, with a preference for the months with highest rainfall (October -April). Clutch size is one or two (van Balen et al. 2011 and references therein).

It is slightly larger than a blue jay.

I couldn’t find much more about this beautiful bird but if you can, please share!

Andaman Treepie (Dendrocitta bayleyi)

I did a previous post on this rare bird but I have found new information, so let’s read about it again, shall we?

According to the IUCN 3.1 Red List, the Andaman Treepie is nearly threatened. It is endemic to the Andaman Islands in India. Since the Andaman Treepie lives within a very limited habitat, it is in danger of extinction due to habitat loss. The IUCN explained further,

Dendrocitta bayleyi is endemic to the Andaman archipelago, India, where it is usually found in pairs or parties of up to 20 birds, or in mixed flocks in tall trees in dense broadleaved evergreen forest. It is uncommon to locally fairly common and while habitat on the Andamans remains relatively intact it is probably secure. However, indications that an increase in human populations and habitat loss is occurring in the archipelago suggest that within the small range of this species natural habitats might rapidly shrink and become fragmented.

It is unfortunate that one of the corvidae family is nearing extinction due to loss of habitat. Can there be no uninhabited places on this Earth? Can we not leave room for the other species?
