In a quick recce around the hotel grounds of the Sol Rio de Luna y Mares we identified some areas of longer grass that hadn’t recently been cut and which contained various Eurema species and Dorantes Longtail Urbanus dorantes. Later these areas were all mown which was a shame as their value as a breeding and roosting area was removed at a swipe. We have spoken to the head gardener Amaury about this and asked him to think about leaving some grass areas uncut which we hope will have an effect. In March the area was much drier than in December and there was a nice uncut area near their vegetable growing area which had several species roosting and a mating pair of White Peacock Anartia jatrophae and a Hanno Blue Hemiargus hanno. There are two other very common species of blues that I will show here so that you can see the differences. All three species can be abundant often flying together in open areas anywhere. The other four species of 'blue' are rare in Cuba.
We also found an area near the beach that was ‘less-managed’ and where there was a nice variety of nectar sources including Bougainvillea. Here we saw our first Mangrove Skipper Phocides pigmalion with its distinctive blue stripes but the real excitement came later in the holiday with the finding of larvae of this species. By chance just before we left England I had come across a photo of a fully grown larva which encouraged me to look while we were out in Cuba. I had kept an eye open for feeding damage in several areas of mangrove without success but one day as we stood near the blue bridge I spotted several partially eaten leaves, and on closer inspection found some turned over sections of leaf with larvae concealed underneath.
The Ixora hedges in the gardens were being visited by Cloudless Sulphur Phoebis sennae and Large Orange Sulphur Phoebis agarithe amongst others.
Although small, it was quite clear what they were from having seen the photo the previous week so that was very fortuitous. Larvae feed nocturnally and hide by day under a specially constructed leaf flap formed by cutting two segments in the leaf edge leaving a central hinge connection which is folded over using silk strands. When the flap becomes too small for the growing larva a new larger one is cut. The day before we came home we went to have another look and opened up one leaf fold again and the larva had grown considerably. We also found freshly laid eggs that had not been there a few days before.
The next few blogs will be about our last two trips, both to the Guardalavaca area in north-east Cuba, in December 2014 and March 2015.
The first thing that most people do when they arrive at their hotel is go to the bar, get a drink and sit by the pool. But to any naturalist the first thing they want to do is get out and explore and get the lie of the land. A quick tour of the gardens at dusk was all we managed the first evening but we were up at crack of dawn the next day, and every day for that matter, for a walk before breakfast. Often this would take us down to the lagoon just to the east of the hotel grounds, over which there was a long blue bridge crossing to the adjacent hotel, the Paradiso. This hotel is rather more expensive than ours, the Sol Rio de Luna y Mares and so, although they are in the same hotel chain, the folk from our hotel are not allowed into the grounds of the Paradiso, although traffic the other way is permitted!
In March the lagoon was clearly being used as a refuelling area by the egrets on their northward migration and it was interesting to see behaviou that I hadn't witnessed before - as the water was too deep to land in both a Snowy Egret and a Tri-Colored Heron had developed the strategy of flying slowly over the water often dragging their feet which would disturb small fish that would be snatched from the water in flight.
Lots of other birds would be calling from the mangroves or flying over but every morning would be different and sometimes it was difficult to leave to head off for breakfast.
Early morning is by far the best for birds at the lagoon with Least and Pied-billed Grebes, Blue-winged Teal, Neotropic Cormorants, Brown Pelican and often eight species of heron present. We have also seen Osprey and Magnificent Frigatebird flying over on the look-out for fish. On our first visit we sometimes saw a man walking about in the water (it’s about 1.5m deep) and setting traps to catch crabs but in March we were rather disturbed to see teams of several men with nets catching fish (and the odd bird as well). This was happening not only during the day but also at night. I suspect this is a new trend rather than a seasonal pursuit and will I fear have an adverse effect on the birdlife.
