About this Site

This page is from the ASIC Peregrine Falcon Zone, click here for more info.

To contact Mathew Rossi, who is updating this site and recording observations, click here.

This web site (www.asic.ca/peregrinefalcons) is a voluntary effort to keep residents and distant falcon followers informed. News bulletins and observation logs are updated regularly as new info becomes available. During some portions of the nesting season, efforts will be made to provide a live video feed, which is used primarily for assisting monitoring efforts, but also for viewer enjoyment.

The most frequently updated site section is the "Latest News" area, which is a running observation log and news feed showing most recent entries first. Periodically, some posts about other nature stories are added for interest's sake. Updates to the Latest News page can be received in an RSS newsreader if you wish.


The resident Peregrine falcons appeared, and started nesting at this location in 2008. The location is a residential building in the Greater Toronto area. The address and identity of the building are not being publicized as a means of protecting the nest, and also out of respect to the residents and private property the nest is located on. Your ongoing respect of this situation is appreciated.

Technology Info:

I develop complex web applications and software by profession. This site is the result of applying those skills for the benefit of the falcons and the community.

The site consists of an easy-to-use main page with a menu for simple navigation to areas of the site.

Entries to the site are made through a web browser from any computer, into a proprietary ASIC developed blog/web site management tool. Postings are created, images added, and the post is then approved for display and shows up on the site.

When running, the video feed involves a number of elements. A video camera is located near the rooftop, shooting through a window in one building, across ~ 80 feet to the nest location. This camera feeds a signal down ~200 feet to the ground floor. The camera signal is then connected to a video device which allows remote viewing, and that device in turn allows remote broadcasting of the signal through the web, which is done from yet another location.


Images are continually shot as opportunities and time allow. All shots are digital and RAW shooting mode is always used for capture. Equivalent focal lengths range from as low as 50mm for close-up banding shots to over 1000mm for longer distance shots.

Photos are post-processed manually including significant cropping, then automatically rendered into galleries using a custom photoshop gallery template.

In 2008, over 25,000 photos were shot on site. Some were used to document various steps in the nesting cycle, some were used to assist in juvenile identification during fledge watch.
