On the way to a three-weeks-birding trip to Ecuador the plane makes a scheduled

stopover on the Caribbean island Bonaire. Therefore I decided to stay for one week

on Bonaire for birding and snorkeling. This was the right decision because Bonaire

offers a wide range of great birds in superb landscape and is one of the best

snorkeling and diving destinations in the world. I didn’t find many trip reports for

Bonaire; the published ones on travellingbirder were quite helpfulfor me. Furthermore

I got in contact with Jeff and Allison Wells at thia website and they offered me some very helpful information.


A car was prebooked from Germany at AB Carrental, Kralendijk via the Internet. It

was a Landwind Xpedition (Class 12) which was very useful when driving the partially

bad roads in the National Park and to the mangroves at Lac Cai. With a normal car

you would have no chance to get to all the good birding places, therefore it is highly

recommended to use an off-road car type for your explorations on the island.

At the tourist information in Kralendijk I got information about available

accommodation and I chose Hotel Rochaline in Kralendijk (rate 60 $ (+ 5,50 $ Tax)

per night).


Now exploring the island could start. During the week I visited nearly all places for

more than one time. 1.) Kralendijk itself holds lots of birds. 2.) From Kralendijk take the

road to the north and via Rincon you get to Dos Pos, Gotomeer and Washington

Slagbaai National Park. 3.) South of Kralendijk are the wetlands around the airport,

the mangroves at Lac Cai, the Salinas and the Pekelmeer.


Some information for an additional place, “Dienst L.V.V.” – Sewage Works, Antriol,

which was found more or less accidental are given here. Antriol is located in the

north-east of Kralendijk. Take the road which takes you from Kralendijk to the Lagun

(east coast, in Kralendijk there’s a sign “Lagoon” you can’t miss). After passing the

last houses some open areas follow and soon you’ll see a big sign on the right side of

the road “Dienst L.V.V.”. Here you have to go to the right and immediately you are in

the good area. Please note: this is a private area; therefore you should find

somebody who is living or working there and kindly ask him for permission to have a

short look over the wetlands to look for birds. During my visits this was not a problem.

Furthermore you are looking most of the time from the car because the birds are

often so close. Just after entering the road you have a quite deep pond on the right

further away from the road and a larger wetland area to the left just next to the road

behind some walls. When passing the farmers buildings you continue the track and

come to a deep pond with lots of dead trees and to the sewage works. This area is

like similar places everywhere in the world, where there’s the dirtiest, smelliest and

ugliest place there are the best birds! Lots of shallow water edged with low reed

attracts different species of waders, rails and songbirds.


Finally I saw 77 species of birds in one week which was very successful. Highlights next

to the Caribbean near endemics and the hummingbirds were an immature Red-footed

Booby, a 1st winter Purple Gallinule, at least nine Soras and three Stilt

Sandpipers. I failed to find any Snowy Plover and Brown Booby, both I expected to

see sooner or later. One real miss was Black-whiskered Vireo but it was not possible to

visit all the good sites for this species in the National Park because some of the roads

in the park were closed, therefore the chances to find this species were limited.


Other species as Crested Bobwhite, Barn Owl, and Grasshopper Sparrow are very rare

or it was not possible to get any recent information where to find them and the time

was limited to explore more on my own.


The birding was superb and the chances for bird photography were excellent. Many

birds were quite tame and it was possible to get quite good pictures of many

species. Therefore I can recommend a birding, bird photography and snorkeling trip

to Bonaire!


The snorkeling was excellent, and with little effort it was possible to get views of many

exciting fish species, cephalopods, and nice corals. I snorkeled at the following sites:

Tori’s Reef; Pink Beach; Andrea I; Andrea II; Red Beryl; Windsock; Kralendijk (harbor

area in front of Dive Center); Klein Bonaire (north side drift snorkel).



01.) Blue-winged Teal. Seen at nearly all ponds during the week. Maximum was 25 in

juveniles) were sitting every day on a wall near the “salt mountains” in the western

successful in the mangroves at Lac Cai on 28.01. in the evening when it was nearly

dark. An adult bird was sitting in a canal just ten meters next to the road and allowed

great pictures with flashlight. On the way back to Kralendijk an adult Night Heron

sitting on the main road but flew off immediately was very probably this species, too.

at least 8 birds were seen at L.V.V. Sewage Works. Very probable much more

individuals were hidden in this superb roosting habitat for rails. Some of the birds were

very approachable with the car down to five meters and allowed fantastic pictures.

25.) Purple Gallinule. An unexpected and big surprise was the found of a 1st year bird

perched in the open next to an Iguana at L.V.V. Sewage Works on 28.01. Probably

the same bird was flushed on 29.01. in nearly the same area where it was seen the

L.V.V. Sewage Works.

46.) Wilson’s Snipe. On 28. & 29.01. a maximum of 6 different birds was noticed at
