Species Composition

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.

Date Selector

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.

Daily Counts

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.

Site Weather

Jewel Basin 2023

This project contains the basic HWI (Hawkwatch International) metadata protocols (flight/observer/weather) for a standard raptor count.


The Jewel Basin Hawk Watch site northeast of Bigfork is reached by a combination of paved roads, dirt road and hiking trails. It generally takes a little more than 2 hours to reach the site from the Echo Lake Café: From Highway 83 (the Swan Highway), turn north onto the Echo Lake Road at the Echo Lake Café and Swan River School. This intersection is about 2.8 miles east of the junction of highways 35 and 83 north of Bigfork. Continue 2.1 miles north on the Echo Lake Road, around the southeast end of Echo Lake, to Foothills Road. Turn right on Foothills Road. Continue 1.0 miles east on Foothills Road to Forest Road NF5392, the Jewel Basin Road. It is signed a little way east of the intersection. This gravel road takes off of Foothills Rd right where the latter takes a 90-degree turn to the north. Once on the Jewel Basin Road, you will continue about 6.5 miles to the Camp Misery parking lot. This road is narrow, washboarded, and steep at times; drive slowly and with caution. It is about 2 ¼ miles from the parking lot to the Hawk Watch site. Take trail 717, which starts as a gated road next to the information board at the parking lot. This will wind its way up to the ridge, and eventually becomes a narrower trail after passing an old burn. A few hundred yards after this trail section begins, you will come to a multiple-trail intersection. You want to continue on toward Mt. Aeneas on 717, the uphill section to the right of the steep jeep trail. There is a trail marker sign about 20 yards up the trail. From this point, you will be on a series of switchbacks that take you to the main ridge. There is a concrete building on the ridge where the trail tops out; to the right is the continued trail to Aeneas. At this point, you will turn left and follow the “goat trail” north along the ridgeline about ¼ mile to the observation point, where the trail essentially ends at the top of a rock face.
