A tetrad by definition is the cardinal number of 3 plus 1. For our purposes its the researh of bird populations, over a defined area, researched 4 times. In layman's terms it means identifying birds, their behavior in a given area to determine population, breeding etc. That way we can know if populations are static, on the rise or in decline. For me its a great excuse to see the english country side and to learn more about the wildlife of the UK.

Over the 3 weeks in England we identified 114 different species of birds. Pretty good eh?!

Some of the farmland would walk to identify birds and their behavior. We covered a specific area over a specific time of 2 hours.

I liked this tree! The lakes district is simply one of the most beautiful places I have been.

Dr Jim Fowler negotiating one of the many styles we have to climb.

And the roads we walked. This is what is so enchanting- you can walk across farmland and really see and appreciate what is on offer.

Green Woodpecker! Why? Well these guys love to peck steel power poles and make enourmous sounds, each trying to outdo the other! Brilliant!


  1. good thing you explained that... i would have had no idea :)
    i like that woodpecker. hes awesome

  2. Hi Laura---hahahah! yes. They produce a book about it. Great excuse for a walk and a vital park of "mapping" bird populations :o)

    The woodpecker and its behavior is very cool imo :o)

  3. Hey Simon
    Cute woodpecker you've got there.. and talking about numbers.. 114 ..not too shabby!!! The views look glorious!!!

    by the way.. now 95.. ciao ciao.. Julie

  4. Nice post mate!
    I should say that, by strict definition, a tetrad is a square 2km x 2 km (hence 4 sq km) of our Ordnance Survey grid system, but you are right in saying that the survey requires 4 visits to each tetrad.

  5. Incidentally, we call the construction in the road in the picture above your list a cattle grid . Do you have then in Australia?

  6. Julie- thanks! hope you get to 100 comments!

    Jim- thanks mate.. yes I realised I had ommited the area of the tetrad

    Yes we have cattle grids and cottages in australia!

  7. 114?? All in 4sq km? Wow, that is seriously impressive! Sounds as though you had a thoroughly good time, as well as putting it to some great use. Glad you enjoyed visiting our shores, when are you coming back again?

  8. Beautiful countryside. Would love to go walking there. Having listened to Jill though, I imagine I would be lumbered with heavy tripods and the like, so maybe not!

  9. Shrinky- oh no! thats 114 species in two weeks as well as the tetrads.

    Kiwi- its not too bad really, once you get the balance point on your shoulder right.

  10. I see you have the same Chinese spammer who visits me. I might tighten up my comments criteria...

  11. Mate, do you know this song about a motor vehicle?

  12. Kiwi- yes drives me niuts.

    Maalie I will check it out

  13. The woodpecker is fab! Amazing countryside - first visited that area a few months ago! Typical, travel the world but don't see own beauty at home

  14. Did you get a chance to listen to that song mate? It's about a motor vehicle, I think you will enjoy it.

  15. Wow, Simon. You're quite the naturalist yourself! What a list!

    Glad you could have such a good time in the UK with Maalie.

  16. it was a great holiday mate!

  17. Simon that's amazing work! But seriously - 4sq km (x4) isn't much to cover for a hiker like you ;-) Just kidding. Have you achieved the same sort of feat in AUssie?

  18. no. its different in the UK. We cover HUGE distances here but its not the same :o)
