About Me

My photo
Canberra-based naturalist, conservationist, educator since 1980. I’m passionate about the natural world (especially the southern hemisphere), and trying to understand it and to share such understandings. To that aim I’ve written several books (most recently 'Birds in Their Habitats' and 'Australian Bird Names; origins and meanings'), run tours all over Australia, and for the last decade to South America, done a lot of ABC radio work, chaired a government environmental advisory committee and taught many adult education classes – and of course presented this blog, since 2012. I am the recipient of the Australian Natural History Medallion, the Australian Plants Award and most recently a Medal of the Order of Australia for ‘services to conservation and the environment’. I live happily in suburban Duffy with my partner Louise surrounded by a dense native garden and lots of birds.

"Good night, and thanks for the tinamou..."

In 10 trips to South America I'd never managed to see a tinamou, to my chagrin. I'd heard them, and on one occasion the group just in front of me saw some walk across the track, but not me. It's possible I've even mentioned the fact to other travelling companions...

They really are a most interesting family of birds, close to the most ancient of living birds. Together with the ratites - the mostly large, flightless runners of the southern continents, emus, cassowaries, kiwis, rheas and ostriches (plus extinct moas and Madagascan elephant birds) - they comprise the grouping known as the Palaeognathae, 'ancient palates'. This refers to primitive palate characteristics which are more reminiscent of reptiles than other living birds. All other birds belong the 'other' grouping, the Neognathae. Some put the ratites and tinamous into separate orders, others insist they are all part of one order of very closely related birds.

Another reminder of the close relationship between rheas and tinamous is the breeding behaviour. Tinamou males call to attract females, one of whom mates with him and then leaves him with a clutch of eggs to brood on the ground,
while she goes off to find another male for another clutch. This is not identical to ratite breeding but is very similar.
The key difference between the two Palaeognathae groups is that the tinamous retain the keel on the breastbone, which is the anchor point for the great flight muscles, and can still fly, though reluctantly and inexpertly. It seems that the ratites broke away early from the tinamous and then diversified in the Gondwanan lands.

There are 47 tinamou species found throughout most of Central and South America, in pretty much every habitat type, but they are notoriously shy and skulking.

One night recently at Napo Lodge within the magnificent Yasuní National Park in the Amazon basin in Ecuador I was about to have a shower prior to collapsing for the night when a knock on the door was followed by "come quickly, I have something you want to see". It was Dani, the lodge-employed guide attached to our group, who had heard about my desire for tinamous from Marcelo, our own guide. He'd seen one roosting nearby a few days previously and had gone to see if it was still using the same site; it was...

With torches we descended into the rainforest on muddy tracks and after a few hundred metres, there it was above the track.
Great Tinamou Tinamus major.This  is a big bird, up to 45cm long and weighing well over a kilogram.
It has been heavily hunted and suffers from forest clearance, but is doing better than some other species.
We didn't stay long, not wanting to scare it off into the night, especially when dazzled by our torches. It was a very special moment for me and one I'll never forget, not only for the wonderful bird itself, but for the kindness of Dani and Marcelo. Of course I still want to see one on the ground in the daytime, but for now I'm very content.

And as a footnote, on the way back we saw another delight that I'd only read about, a beautiful coral snake. These are highly venomous, but small and not readily encountered.
Coral Snake, probably Micrurus sp., disappearing under a log.
There are some 20 species in Ecuador and I can't hazard a guess as to the species, but it capped a memorable night.

It's a good feeling when a sighting is finally achieved!

I saw Great (2 locations), Little and Highland Tinamou in Costa Rica this year. Brief but clear views of each. So perhaps Costa Rica is a 'better' place to see them as I don't have your astute bird observation skills!

Thanks HW - it is indeed!

Les, putting aside for now your unjustified modesty as a birder, it certainly seems as though CR is a place for the tinamou-deprived. On the other hand it might just be that they've been of those bird 'blind spots' that we all have and others just don't have my problems seeing them!
