The sightings you see here are being collected on a tablet by a biologist out in the field.
Hover your mouse over the points on the graph to see more details. Click on different species in the legend to show or hide them on the chart.
If there's nothing showing, it may mean that this site doesn't have access to the internet or isn't counting right now.
No Reports in the Last Two Hours
Species composition changes over time depending on weather, seasons, and many other factors. This chart displays the composition over a time period you select.
Click on pie pieces to see more detail. If there are more than seven species, click on "Other" to see a breakdown of the rest.
Many sites have a protocol that is designed to maximize finding particular species. If you select "Focus Species," only these species will be shown.
The control box below the pie chart lets you select a date period for the chart.
You can push the buttons "1d," "1w," or "1m" to zoom the graph to 1 day, 1 week, or 1 month.
The graph shows the overall volume seen on each day. You can drag the sliders on each side of this graph to adjust the start and end dates.
August 11th to September 25th
The time shown in the top row is the start of the one hour period.
Choose a date to load the hourly table for that day. Only days that have data are shown.
These charts show which species are most numerous at different parts of the season. Hover your mouse over a chart to see the number for a given day. The right column shows season totals and the left side shows the maximum for a single day. Each graph is scaled so that the single-day maximum is the highest point on the chart.
- Focus Species: Show the highest priority species at the top of the list.
- Taxonomic Order: Sort the species by their scientific classification.
- Alphabetic Order: Sort the species by their common name.
- Abundance: Sort the species with the largest number counted at the top.
Mt Brown Hawk Watch 2023
In celebration of the Year of the Bird (2018), Glacier National Park launched a new Hawk Watch Program where park biologists teach volunteers how to count migrating raptors. Each year, Golden Eagles migrate from northern breeding grounds to warmer climates. One of the most important North American Golden Eagle migration routes passes directly through Glacier National Park along the Continental Divide. Large numbers of other raptors also use this migration corridor during the fall and spring months.
Hike approximately 4.5 miles up the Mount Brown Trail (roughly 4,000 feet in elevation gain). The count will be held on specific days in September and October from 10 am to 4 pm. If fire conditions do not allow access, an alternate site may be identified.
Glacier National Park
The Glacier National Park Citizen Science Program engages park visitors, students, and staff in collection of scientific information that would otherwise be unavailable to resource managers and researchers. Since 2005, the Citizen Science Program has invited members of the public to assist in biological research while recreating in the park.
