Embedded Timelines: Can I listen to new tweets?


Is there any way to “listen” to updates from an embedded timeline? I am building a site that will show an embedded timeline with a custom search for a hashtag, however I would like to put a marker on a map whenever the timeline gets a tweet that is geolocalized.

I am guessing the answer is to build my own feed using the Twitter API but I was curious if there’s any way to “listen” for new activity in the embedded timeline.
