Birds and Mangroves

I kayaked over to the Carlo Island roost site yesterday. I wanted to see if I could find a way through the mangroves to the other side of the Whimbrel roost and also to the north side of the bay where we went in a 4 wheel drive vehicle last month. No, I could not get to the other side of the Whimbrel roost but, Yes, I found a way to the north shoreline.
There are a number of different mangrove varieties in this area with quite different growth habits in different areas.
The mangroves where the Whimbrels roost are quite distinctive. They don't have rounded crowns as most mangroves do but almost look to be broken off at the same height - although there are some higher branches where Whimbrels roost and watch for any disturbances. There are thick stems/trunks visible so they are not just young trees. There is new healthy growth all through the area so they are not dead or dying trees. It is only in the roost area that the trees are like this. Surrounding areas have larger well-shaped trees as well as much smaller and younger trees. I would be interested in any opinions as to the reason - from those who have more knowledge about mangroves than I do.
When I kayaked through the mangroves to the north shoreline I found the Godwits and Eastern Curlew were roosting in the shallow water at the edge of the bay. I stayed well away so I didn't disturb the birds - the Godwits stayed where they were but some Eastern Curlew flew.
I saw a number of Orange Mangroves (Bruguiera gymnorhiza) with both flowers and fruit on them. The red colored flowers made a nice contrast with the dark green leaves.
Next to these Orange Mangroves were some with white flowers (not yet open) and much longer fruit - Red Mangroves (Rhizophora stylosa) I think - although I am still having trouble identifying some of the mangroves.
While paddling slowly and quietly through these mangroves I saw a Striated Heron. This one let me get quite close without showing any signs of being disturbed. It turned and looked me over and then went back to looking the other way.
The round trip was a bit over 6 kilometers and the hardest part is always getting the kayak back up on the car! This photo is looking from the Carlo boat launch back towards Tin Can Bay.
