Indeed, Carl. I bypassed the pager system part and went straight to the map.

Interestingly, you can zoom in down to individual house level on the map to see the location of the sightings. For example, the Eleonora's Falcon in Southend (Essex) was reported partway along Harcourt Ave.

Of course, you have to subscribe at the rate of 70p per day to get the full details ....

Regards, Laurie.

Laurie,

I think there would be a problem with a pager system such as this. I think, and would be happy to be corrected, that Telstra, in their wisdom, axed their pager service some years ago. The only pager systems in Australia now are private local and private area networks. The LAN's are generally restricted to sites such as hospitals, while the WANs are used by emergency services, usually by piggy-bqcking the signal on the various emergency service radio networks.

I think Telstra dropped the pager service because they regarded the mobile 'phone service as more "efficient" or perhaps that was more profitable.

There is no reason why a such a service could not be based on text messages to mobiles though.

Cheers,

Carl Clifford

http://www.birdforum.net/sightingsmap.php is an example of what can be developed when there is a critical density of twitchers in a region.

Interestingly the categories are uncommon, scarcity, rarity and mega- rarity. The current map shows 4 mega-rarities, which may indicate that the scale might need to be re-calibrated.

Regards, Laurie.
