To the Islands in the North

Week 20, 18 May 2012 - Boubyan and Warba Islands

We were fortunate to be able to visit Boubyan Island courtesy of the Kuwait Coastguard, to conduct a census on the birds that breed on this large island in the summer. What makes this fantastic, is that access to the island is restricted as it is a military area and in general the birds themselves appear to have no visible predators at this time of year. In general, attrition of young would be attributed to the harsh and overbearing summer temperatures.

After driving to the coastguard station, where we were made very welcome, we departed on the boat and headed in a northerly direction on a channel between the island and the mainland. A distant Osprey was observed sitting on a bouy, but more interestingly a lone Socotra Cormorant was also seen. I'm not aware of any records of this species this close to Iraq. It is known that there are two sub-populations, with the northern population breeding on the islands of the Gulf coasts of Bahrain, UAE, KSA and possibly Iran (but breeding has not been confirmed since 1972)

When we reached the bigger channel between Warba and Boubyan a few Lesser-crested Terns made an appearance

On route we did see a few areas where birds were breeding, but due to the tide we could not get close enough. Finally though, we found a mixed breeding colony and spent an hour enjoying the amazing spectacle of this mixed breeding colony and marvelled how these species shared the same stretch of beach in what seem harmony.

On the beach itself, almost all the Slender-billed Gulls had young and only a few were still sitting on eggs in between the sabkha. We estimated 2000+ birds in this area

In amongst the mass of Slender-billed Gulls, we picked up a few Gull-billed Terns, also with young

A few Caspian Terns which also breed on the island were seen flying by overhead

Just off the beach the available sabkha habitat was shared by the larger Herons who all had raised nests built on top of the sabkha. There were a few Grey Heron with young

Slightly more Eurasian Spoonbills, also with young

But the majority were Indian Reef Herons of both forms....here some dark forms with dark young

and some light forms with light young. We found it quite interesting to see an adult regurgitating food to its brood of 3 demanding chicks.

and a light and dark form juvenile together

By now the temperatures had risen and we needed to move to get some relief from the heat, but not before checking the massive (2000+) Crab-plovers that didnt allow us to get too close. Only when editing my images, did I notice a juvenile Crab-plover in just one of the images - I'm guessing that other juveniles were still in their burrows which we also didnt see.

We had hoped to see some Dolphin on this trip and were rewarded with a pair of Indo-pacific Humpback Dolphins on the way back to the Coastguard Station and a great sighting to end a rewarding day.
