2016 - World Yearlist Record Attempt (1 Viewer)

[Jon Turner]

6371 now, 35 species in Mexico in two days, the right average.

So exactly 17 per day. No pressure then!

Actually 40 in 2 days. He probably uploaded once around noon and then in the evening some extra species.

Piece of cake then! :eek!:

 

[Paul Chapman]

Noah was 173 species from 17 days in Mexico. I'm expecting Arjan will travel more? My hunch is that he will be behind by the time that he reaches Vietnam but that will be a nail-biting ride where he can pick up the pace?

All the best

6396 four days in Mexico (59 added)

75 from 5 days in Mexico (15 per day, keeping it touch and go)

 

[Brian J Small]

Monthly breakdown as follows - May and June were a weaker months; July was very good. Average of c. 480 in last four months - if he keeps this up it will be close...

NOV - c. 410 so far
OCT - c. 450
SEPT - c. 610
AUG - c. 440
JUL - c. 950
JUN - c. 280
MAY - c. 390
APR - c. 810
MAR - c. 735
FEB - c. 500
JAN - 816

I know both Noah and Arjan count(ed) heard only, but is there anyway of working out what proportion of the total? Are they coded differently? I would guess at 10-20% but that is...a guess.

cheers, alan

 

[Maffong]

Well, in the Ende Noah only had 331 heard onlies, so around 5% of his total

Added 4198 Sick's Swift Brasil
and 6176 Northern Mealy Amazon Guatemala

ok thanks, I had not spotted that

First report of Rosy Finches at Sandia peak over the weekend (if that is what Arjan is targeting in NM):

American Three-toed Woodpecker also present.

Arjan is now (29.11.) at 6.447 species:
http://world.observation.org/arjan.php

He has seen 446 species so far in November and has one more day to go.

He presumably needs around 540 species in December to reach 7.000, that will sure be a close run. He has exceeded that monthly rate just in five of eleven months yet. But he will have an change in continents at the very end that will help in raising the final rate...

It will be very tense for him - and us (!) - in the last days of December I suppose! Good luck, Arjan!

Arjan has already seen 109 species in seven days Mexico - so he will presumably end far beyond the prediction of 150 species after eight more days there...

 

[temmie]

He may surprise me, but he did a pelagic and is adding more and more US birds, so less potential over there. I also feel he is planning a bit too much time in the US. He probably needs to, in order to cover the whole country and including all the travel time, but it will lower his average.

 

[DanielDoer]

He may surprise me, but he did a pelagic ...

Thanks for the hint (I had overlooked that in the species list).

But he still can do a pelagic in the Atlantic Ocean from US and in northern pacific ocean from Japan to increase the average

It's interesting to me since I think I was one of the first to question if 7K was possible (most dismissed it at the time) that it now seems to be the target!

Even if Arjan doesn't quite make it, it is certainly a realistic target using the two previous attempts as a template for an even sharper itinerary.

Agree,
hope he get's there, it will be a huge target to beat for any future challenger.
