If you are just birdwatching on the Cayos you should be able to manage on your own armed with the Helm guide.
You don't even need a car-there is a hop on hop off bus between Guillermo and Coco.
Get off as soon as you land on Guillermo near the bridge by the dolphin place.The most productive lagoons were here just west of the bridge.If you carry on walking east all the lagoons had something of interest on either side of the road.
When you see the tacky old power station on your left head for the next track inland on your right.This takes you to the west of the Sol Cayo Guillermo Lagoon.This can be viewed by turning right as it skirts the northern edge-it was one of the best lagoons on the island.
Take plenty of insect repellent!
Stayed from 5/4/2013 to 12/4/2013
Copy of my report
Cayo Guillermo
A small island only 18 square kilometres but around 85% is mangrove forest,lagoons and swamps.
There are just 4 hotels on the island.
The Sol Cayo Guillermo Hotel
A typical Cuban AI hotel well landscaped with 1000's of plants and trees.
It borders a huge mangrove lagoon and also the sea and beach.
Great food and drinks package and a pleasant friendly atmosphere.
Getting around.
An open top bus plies it's trade between Cayo Coco across the causeway ,past all the Cayo Guillermo hotels to the end of the island at Playa Pilar.
Return costs are $5 return.
Otherwise you can easily walk to any of the places I have mentioned apart from Playa Pilar.
Playa Pilar
A dream Carribean beach at the western end of the island.
From the bus stop and car park head west to Zona La Punta an idyllic area far from the sunbeds.
The star bird was a Black Skimmer sitting with the Laughing Gulls at Zona La Punta..
I didn't expect to see it as it was described as both rarity and nocturnal.
At Zona La Punta I saw 2 Frigate Birds, Great Blue Heron.Great Egret,Snowy Egret,Little Blue Heron,White Ibis,10 Royal Tern,Double Crested Cormorant,Spotted Sandpiper and several Pelican..
A flowering cactus attracted 3 Cuban Emerald,a Cape May Warbler,a Parula and a Prairie Warbler.If you see a flowering cactus its well worth having a good look.
Along the sandy track to Zona La Punta an Eastern Wood Pewee appeared along with a Crescent Eyed Pewee..
The area around the car park and boardwalk was great for birds.
They included 4 grounded Turkey Vulture,Northern Parula,Prairie Warbler,Common Yellowthroat,Cuban Emerald.Gray Kingbird,Greater Antillean Grackle,Crescent Eyed Pewee,Northern Mockingbird,Zenaida Dove and my first Cuban Bullfinch.
The Punta Playuela Track
Every time a took this walk something new turned up.
From the northern path along the Sol Cayo Guillermo lagoon keep on going north west keeping the sea to your right.
Just before you reach the deserted beach there is a rough track to your left marked by a wind blown wooden parasol.
This track soon comes to a dead end but it was a great little area for birds.
After pishing about a little,a Gray Catbird appeared momentarily.this was my 650 lifer so another milestone passed.
My first and only Cuban Gnatcatcher was here along with an Oriente Warbler which was my sole sighting.
There was also an American Redstart among the coastal scrub as well as the common Prairie Warbler and Palm Warbler.
Two White Winged Dove were always about along with some Mourning Dove.Two American Oystercatcher were on the rocks before the beach.
The seaweed strewn beach was wonderful.
The All Inclusive crowd seldom ventured this far and we usually had the beach to ourselves.
The main attraction were two Piping Plover which were not only supposed to be rare but also endangered.They were here every day with two Wilson's Plover.Other birds seen here were several Turnstone,a Spotted Sandpiper and 3 Sanderling.A Red Breasted Merganser put in a cameo appearance one morning.There was a Semipalmated Plover present on one morning,
Common Blackhawk was regular along with,Turkey Vulture,Pelican, Royal Tern and Laughing Gull.
The Cayo Guillermo Lagoons
As you enter the Cayo there are lagoons on both sides of the road all the way to Playa Pliar about 8 kilometres away.
The big attraction was Flamingo Lagoon ,the second lagoon on your right as you head west.
There were at least 50 Flamingos most days.
The rest of the lagoon and muddy edges was teeming with birds including,Great Egret,White Ibis,Tri Coloured Heron,Green Heron,scores of Least Sandpiper,as well as Lesser Yellow Leg,Short Billed Dowitcher,Willet,Stilt Sandpiper,Black Bellied Plover, two Semiplamated Sandpiper, Killdeer,Blue Winged Teal,Common Moorhen,Barn Swallow, and Laughing Gull.
The usual Common Blackhawk was seen and a Crested Caracas was reported to be further down the road one day.
A Palm Warbler and Yellow Warbler were seen in the bushes
I saw an American Crow one morning which surprised me since it wasn't even mentioned in the Helm Guide.
All the lagoons were worth checking as the situation changed from day to day.
The Sol Cayo Guillermo Hotel Lagoon
This was the last productive lagoon as you travel west.
It is the only one not viewable from the main road but the public can access the northern track.
Just turn right past the power station and take the sandy track till you turn right to walk along the northern track.
All the birds mentioned can be seen from this area or anywhere from the hotel grounds where they meet the lagoon.
Sadly the hotel removed the resident crocodile in case it went all inclusive and ate a guest.
Health and Safety gone mad if you ask me.
It was the only lagoon where I saw the Roseate Spoonbill.
I recorded- Flamingo,Roseate Spoonbill[6 maximum].Green Heron,Snowy Egret,
White Ibis,Little Blue Heron,Reddish Egret,Stilt Sandpiper,Cattle Egret,Great Blue Heron,Killdeer,Least Sandpiper[maximum6]Semipalmated Plover,Turnstone,Spotted Sandpiper,Royal Tern[10 maximum] Frigatebird,Double Crested Cormorant,Laughing Gull,Turkey Vulture,Common Blackhawk,
The Sol Cayo Guillermo Hotel Grounds
The four hotels on the island a very similar.
There were lots of plants,trees and lawned areas as well as the extensive beach area.
Apart from the birds in the abovementioned Sol Cayo Guillermo Hotel lagoon I spotted the following from the rest of the hotel-
Laughing Gull,Ring Billed Gull,Frigate Bird,Pelican,Turkey Vulture,Common Blackhawk,Cuban Green Woodpecker,Crescent Eyed Pewee, Cuban Emerald,Prairie Warbler,Northern Perula,Common Yellowthroat,Palm Warbler,Cape May Warbler,Mockingbird,American Redstart,White Winged Dove,Ground Dove,Mourning Dove,Eleinda Dove,Greater Antillean Grackle,American Kestrel,Collared Dove,Loggerhead Kingbird, Northern Waterthrush,House Sparrow
