Bird Atlas - Winter 2

The second winter starts tomorrow. Let's build on the great start to the Atlas in the York Region and get minimum coverage for TTVs in these squares: SE53, SE57, SE64, SE73, SE75, SE76 and SE77. You can see the available tetrads on the Atlas website.

I also need volunteers to do Roving Recording in all areas. The species lists will be available online soon once there has been an upgrade. This includes nocturnal visits to listen for owls etc. Please let me know if you have done a nocturnal visit as I can only see if there's been one without hearing or seeing anything.

Have a look at http://blx1.bto.org/atlas-results/allocyork.html for current regional results. Note the % Species Richness indicator.

The main batch of paper TTV results from the Breeding season have been input and are in the process of being checked. So they should appear on the database early next week.

Review & validation functionality will be added soon as well. New servers are having to be installed to allow this to run efficiently. The website will be down for 2 or 3 days to allow the upgrade - news of this when I have it.

Enjoy your Atlasing.

Bird Atlas - the second winter


The first Breeding Season has now ended and, like the first winter, volunteers put in a great effort to cover a large number of tetrads in the region. Many thanks for your hard work. Let's keep the momentum going!

Regional results from online returns show breeding season figures of 96 tetrads covered for the Timed Tetrad Visits; 79 of these twice. Last winter in the York Region we made timed visits to 106 tetrads, 101 of which had two visits. If you have results still to enter, please can you do so as soon as is possible for either season.


We are now less than a month away from the start of the second winter for the Bird Atlas.

If you did two vists to your tetrad(s) last winter, very many thanks, this is now complete. Perhaps you could take on a different tetrad this winter?
If yours is one of the 5 with only one visit, please try to get the second one done this winter.


The following 10km squares especially need more Timed Tetrad Visits to be done this winter take them to the minimum coverage:

SE53, SE57
SE64, SE67
SE73, SE75, SE76, SE77


Alternatively, why not make Roving Record visits to boost the species lists? The following squares have a list of less than 80 species from the first winter:

SE53, SE55, SE56, SE57
SE66, SE67
SE73, SE75, SE76

But records from anywhere within the region are most welcome.

In addition, each 10km square needs to be visited, using the Roving Record method, after dark to pick up nocturnal species. Can you let me know if you do one of these?


Validation functionality will be added to the Atlas website soon. This will allow me to see which species are missing from our results and so these can be targeted in the future.


Please request TTVs via the website or drop me an email.


Enjoy your Atlasing.
