2016 - World Yearlist Record Attempt (5 Viewers)

[Paul Chapman]

No doubts at all that there will be errors amongst those!

All the best

 

[dalat]

My guess: 2 days Cat Tien and 1,5 days Dalat.

And Dalat would of course be a worthy place to finish such a great year :t:

No idea, but respect for all those hours spent on your calculator there Paul ...:eek!:

Serious note - some of those do look like rather unlikely if you take the %'s only ... wondering how much a year-listing effort goes on in eg Japan, and hence if January (presumably dec or jan won't make much difference to likelihood of wintering birds being present, ease of connecting?) would show much difference? Presume also that he can successfully target some birds you'd otherwise not easily see ...

Arjan is at 6.506 species now:

Good progress in Mexico!

Data is totally lifted off eBird. No calculator required. It is percentage complete checkists so if a record is input off an incomplete checklist, it represents 0%.

Low percentages can clearly be targeted at specific locations.

And now to something completely different:

Is there a thread on birdforum on the WP big year effort for 2017?, see:
Https://bigyearwp.com

Because otherwise I will fall in a very deep hole on new years day after two years of intensely attending Noah's and Arjan's world big year attempts...

Yes - here:-

I had almost finished a WP species list spreadsheet with codes for different statuses eg widespread resident, restricted resident, rare resident, etc which I'll upload there.

Certainly easier to keep track of that one.

All the best

 

[Paul Chapman]

Currently 6,514, with four days to go in Mexico, he has 60 species left that Noah recorded there (Code 1 - 23, Code 2 - 10 & others - 27) and then 36 species that Noah recorded in Jamaica.

Now, 148 species seen by Noah in the USA that Arjan is yet to see - Code 1 - 120, Code 2 - 26 & others - 2). Also 35 other Code 1 and 60 Code 2 species...... Of the USA species, 25 of those are available in Japan.

Then maybe 75 of 89 possibles in Japan, 45 of 56 possibles in Taiwan and 60 of 73 possibles in Vietnam?

All the best

What about a 24 trip to Dom Republic - you could easily slot this in in/out Miami or New York. Surely 30-40 available?

cheers, alan

He already did a short stop in DR - 10 species.

While I'm sure the incidence of observation in e-bird checklists can provide useful data, a very quick eyeball of the Asian ones suggests they are of limited use in predicting what species a competent visiting birder is likely to see on a well-planned birding trip. Take Japan, for example. Hooded and White-naped Cranes are both around the 3% mark, which would imply that there is a very low probability of seeing either. In reality, they are both impossible to miss if you go to Arasaki (assuming you are able to spot >10,000 birds crammed into a field a few metres away)!

Of course, you wouldn't use them that way. The percentage is of the number of completed checklists for the entire country in the relevant month. It is a means of identifying targets. Obviously the higher the percentage ordinarily the more widespread the species.

If there is one site for a species out of a thousand and all sites are visited equally, the percentage of completed checklists would be 0.1% but clicking on the map and the checklists would provide you with the information.......

 

[JustinJansen]

6529 now and already 191 species in Mexico. If I count Paul's numbers and he sees the maximum he falls 25 short of the 7.000.

I don't know any birder who would use ebird in the way you describe. There are much easier ways of identifying targets - reading old fashioned trip reports being the obvious one. Birdquest tour reports are a common starting point.

The real value of ebird, for the world birder at least, is the ability to find recent sites for difficult species, together with the potential for contacting the observer to get more specific gen.

Have to agree with this - on the occasions I use ebird, this is precisely the means I use it.

If Arjan had used eBird throughout and selected Target Species for instance for a hotspot in Vietnam, it would provide him with the species recorded at that site in December by others within the system and he could then click on the species to identify each of the relevant sightings. He is not in a traditional trip planning mode - where do I want to go? What species occur there? Which of those do I either really want to see or I need? What is the best way of seeing those etc?

He is in more of a non traditional situation. Similarly, for instance, if I was going to Italy on a trip for whatever reason, I may be interested in finding out what species are in eBird as occurring in Italy and checking whether I will be close enough to see any of those. (Just looked - it is seven species and one of those is only on Sardinia and four of them are Category C species.)

All the best

 

[Paul Chapman]

And of course that took less than 5 seconds as would checking how many targets, I would have anywhere else. It would take Alan (downthread) a similar period to check what targets he had in Vietnam.

All the best

 

[Pedro Ramalho]

Take Japan, for example. Hooded and White-naped Cranes are both around the 3% mark, which would imply that there is a very low probability of seeing either.

Localized species have always a low percentage. But 3% is actually very high, meaning that 3% of the total lists for a given period have the species, for a localized species that basically saying that is guaranteed.

eBird target function is useful, but requires care using it, it’s good to see what are the common species and what are the specialties, and then you can narrow the search for a more restricted area and see if there are recent sightings.

Also you can use the alert function, if a bird that you need is seen in the area you get a alert.

The system have various faults, but it’s an easy and fast way to check at are the species of interest in an area. It’s good to get a list and then starting to locate the best places.

6514 + 60 + 36 + 148 + 35 + 60 + 75 + 45 + 60 = 7033
