We also found an Orange-fronted Parakeet:
Limpkin:
And just before entering the park itself, a Bare-throated Tiger-Heron:
Helen had picked a Rufescent Tiger-Heron as a target bird before the trip (not realising we weren't going to that kind of habitat) so this counted as trip bird sighting. Splendid looking birds they are too.
Another 'road to' bird was the Eastern Meadlowlark:
Picking up spilled seeds from the agricultural vehicles traversing the area.
Crested Guan:
They appear to have ploughed the soon-to-be marshland, at a guess to improve the habitat for migrating ducks and geese and other water birds. You can see the dry forest covering the various rocky outcrops too:
Above the road a Ferruginous Pygmy-Owl:
The abundant Great-tailed Grackle:
Another road bird of prey, this a Hook-billed Kite:
A particular favourite of mine is the Turquoise-browed Motmot. They are superbly colourful birds:
In a small pool, one of the last bodies of retained water, a Northern Jacana waded around:
The water levels on the marshes were well, absent, so the birds typically encountered here were all elsewhere. The river was in full flow still though:
And in a tree right by the water's edge White Ibis:
On the way back we saw our first Scissor-tailed Flycatchers of the trip:
Which I duly found, in this case a Yellow Warbler:
Finally what I believe is a Plain-capped Starthroat was perched in cover:
Palo Verde would be better in the wet season with many more birds and species of birds, but we still enjoyed our visit. It was to head to our accommodation in Tamarindo.
