The Bird’s Eye view is/was one of the nicest bits in Bing Maps (get there quickly, at www.bingmaps.com – did you know you can type simply bingmaps in the address bar of Edge or Chrome, and press CTRL-ENTER to add the www and .com bits?).
The Eagle-eyed amongst you may have spotted that some changes have happened… clicking on the drop-down control to change the map type no longer shows Birds Eye – instead, if you right-click on a point on the map, you may get the option of viewing in bird’s eye view, and maybe streetside (though don’t expect the same level of coverage of Google Street View, at least if you’re outside the US).
If the bird’s eye option is greyed out, that means the view is not available – or no longer available, as out of date maps have been temporarily removed from the platform. Or at least removed from being easily found – if the missing area is on a boundary between data sets that are being updated, it may be possible to find a nearby place, and scroll across to find the view you’d originally searched for.
If selecting the view doesn’t work for you, try clicking on the “hamburger” menu in the top right, and change the country setting to be United States… whereupon the bird’s eye will work, but the Ordnance Survey view will disappear.
Of course, another aerial view option would be to turn to Google Maps – one tip for using the aerial view (activate via the Satellite icon in the lower left), is that if you see older images, you may well be looking at a map layer associated with the 3D view, where the service renders the view by “underlaying” building shapes with the images. Handy in a city, maybe, less so in the countryside.
In some cases, more recent images are available if you switch 3D off, by going to the hamburger menu in the top left; try disabling 3D to see what difference that makes to your aerial view.
