Greenlaw Mountain Hawk Watch

Greenlaw Mountain Hawk Watch Atlantic Canada's only on-going hawk watch gathering important data on raptor migration

The Greenlaw Mountain Hawk Watch program, a project of the Saint John Naturalists' Club, provides important information on the migratory patterns of raptors and changes in their populations and migratory behaviour.

Greenlaw Mountain Hawk Watch’s 2025 Annual Report is now online, highlighting 5,472 migrating raptors counted over 43 days!

This season saw above-average numbers of Turkey Vultures, Bald Eagles, and Northern Harriers, while several other species continued long-term declines.

As always, migrating raptors were observed in close, up high, out on the horizon and on occasion, moving below the watch site.

Observation Period: 10:30AM - 3:30PM

Observers: Todd Watts

Weather: A blanket of relatively low clouds covered all but a little sliver of sky through the first couple hours. By mid-afternoon skies were nearly cloudless. Wind NW 10 km/h, building to 20 and gusty while becoming WNW. Rh 80% dropping to 57. Temps -1 to 3.

Notes: Hard to find migrants today. It’s late though, so no big surprise.

Highlights: Good viewing of a couple Northern type Red-tails.

Greenlaw Mountain Hawk Watch Report for Thursday November 13, 2025:

Counts (migrants)
Turkey Vulture 1
Bald Eagle 13
Sharp-shinned Hawk 1
Red-tailed Hawk 7
Golden Eagle 1 (immature)
unknown eagle 1
Total 24

Observation Period: 11:00AM - 3:15PM

Observers: Todd Watts

Weather: Cloudy with some sun for the first hour, then brief sun around 2PM. Wind NE 5 km/h, increasing to 5-10 while shifting to N. RH 78% dropping to 68 before building to 75. Temps 4-5 degrees.

Notes: Immature Golden Eagle 11:01AM. A great way to start the day. This individual appeared to be a first or second-year (bold white tail band). Two large accipiters were being viewed when the eagle moved through the field of view (this was during the first scan of the day). They appeared to be Cooper’s Hawks, but could not be relocated. Eagle activity was higher than average throughout the day with as many as 7 observed within a single field of view (immediately after the Golden moved through). At least 3 adults and 1 second-year moved around the area (the actual number may have been significantly higher). 5 of the 7 Red-tails observed today arrived after 2PM. Most of the migrants were distant, which is typical of light winds near the end of the season (light winds during earlier portions of the season are less likely to produce distant raptors).

Highlights: The third Golden Eagle of the season!

Birds going for the decoy: None

Raptor interactions: Sharp-shinned Hawk and Bald Eagle, Bald Eagle and Bald Eagle (aggressor listed first)

Non-raptors: Migrants included 21 American Crow, 9 American Robin, 16 Red Crossbill, 40 finch species, 16 Red-winged Blackbird

Tomorrow: Looks like NW winds with clouds and sun. Temps around freezing moving up to 3-4 degrees.

Observation Period: 11:00AM - 4:00PM

Observers: Todd Watts

Weather: Cloud-cover 100% at the start reducing to 75-85%. Wind West 25-30km/h with gusts to 50. Rh 71% dropping to 60%.

Notes: Very heavy headwinds kept birds down. Even the eagles struggled at times to make headway. Several hawks turned around after encountering blasts of wind coming across the open river valley. The Osprey was our first ever November record.

Highlights: An immature Cooper’s Hawk put on a good show as it popped up seemingly out of nowhere to harass a low flying Turkey Vulture over the site.

Birds going for the decoy: Merlin

Raptor interactions: Cooper’s Hawk and Turkey Vulture, Merlin and Red-tailed Hawk, Bald Eagle and Bald Eagle (aggressor listed first)

Non-raptors: The only migrants observed were 6 Double-crested Cormorant. Robins and crossbills moved around a bit, but it couldn’t be determined whether or not any moved across the very windy river valley.

Tomorrow: Looks like West-northwest to Northwest winds, clouds and some sun. Winds should be lighter especially during the afternoon. Could be a good day for some late season migrants.

Bald Eagle 2
Sharp-shinned Hawk 3
Red-tailed Hawk 2
Merlin1
Unknown raptor 1
Total 9

Observation Period: 10:00AM - 4:00PM

Observers: Todd Watts

Weather: Cloud-cover 95% at the start, reducing slightly before a blanket of low clouds moved in from the east, covering 100% of the sky (morning hours). A bit of the interior fog still visible at 2PM as it clung to a hilltop. Some clearing during the second half of the afternoon. Wind E around 10km/h with gusts to 20, shifting to NE as the clearing occurred.

Notes: If there was any hope for a decent number of hawks today, it sailed away as the low clouds backed in. A resident goshawk, 3 or 4 eagles and a hunting red-tail made brief, distant appearances. Quiet skies overall. No vultures sighted today. We will almost certainly see more of them, however the locals seem to have left.

Highlights: Male Merlin putting on a great show as it went for the decoy and circled the site repeatedly.

Birds going for the decoy: 1 Merlin

Raptor interactions: None

Non-raptors: Migrants Double-crested Cormorant 290, American Robin 65, 'blackbirds' 30, Red Crossbill 2. Eastern Bluebirds heard but not seen.

Tomorrow: Looks like a repeat of today is possible. Low clouds will cancel observations. A strong front is expected at the end of the week, possibly bringing improved conditions after its passing. Pushes of Red-tails tend to occur in November. Other raptors will be seen.

Counts (migrants)
Bald Eagle 9
Northern Harrier 1 (male)
Sharp-shinned Hawk 3
Red-tailed Hawk 20
Unknown raptor 1
Total 25

Observation Period: 10:00AM - 5:00PM

Observers: Todd Watts

Weather: Cloud-cover 95% reducing to 10% during the morning, then low clouds covering 100% of the sky for most of the afternoon. Wind NE 20-25km/h with gusts 40+, slowly diminishing during the afternoon. Rh 89% dropping to 72%.

Notes: Some extremely distant birds before the low clouds, then next to nothing. Raptors that were seen tended to appear well to the north without first being seen to the east or northeast (unusual). It seemed that they were staying away from the low clouds near the coast. Only four of the Red-tails were close enough to assign a subspecies. All were Eastern/borealis.

Highlights: A real bruiser of a female goshawk with a full crop appeared very low over the site putting on a great show while she hunted (just above the trees). She was eventually escorted to the SW by a male Sharp-shin (great low altitude comparison of these interacting birds). Both were lost behind trees and not counted. This low altitude interaction on its own would have been worth the walk for most people.

Birds going for the decoy: None

Raptor interactions: Sharp-shinned Hawk and American Goshawk, Bald Eagle and Bald Eagle (aggressor listed first)

Non-raptors: Migrants included 175 Double-crested Cormorant, 365 American Robin, 35 finch species (likely Red Crossbills), 30 'blackbirds'

Tomorrow: Looks like lighter NE winds, clouds and sun. With a little luck, the clouds will be higher allowing more birds to move or at least move closer to the site.

Weather: 90 to 100% cloud-cover with showers arriving a little after 2PM. Wind generally 1-3mph, mostly from the WNW. Rh 94% dropping to 65 before increasing as rain developed.

Notes: Pretty flat, cool and damp for the first couple hours resulting in only 3 migrants before Noon. Hardly a vulture in sight even after raptors began to fly (very different than yesterday). Eagles were moving before the showers developed. Rain brought things to an early end. Interesting cloud formations added to the experience.

Highlights: Excellent viewing of a low and close Northern type Red-tailed Hawk. Nice viewing of a low and close female Northern Harrier. Adult American Goshawk displaying over the site.

Birds going for the decoy: None

Raptor interactions: Sharp-shinned Hawk and Red-tailed Hawk, Common Raven and Red-tailed Hawk (aggressor listed first)

Observation Period: 10:15AM - 6:00PM

Observers: Todd Watts, Richard Blaquiere (for most of the day)

Weather: Virga in the area during the morning (radar images of this caused a delayed start). Cloud-cover 90-95% till early afternoon, then cloud-cover ranged from 35% to 85%. Lost the sun sometime after 4PM. Wind 5-10km/h mostly from the WNW. Rh 83% dropping to 55.

Notes: The morning and the last hour were very slow. Vultures arrived in larger groups today. Adult male and female goshawks displaying overhead (residents). The migrant was a juv. Lots of low birds today, often close. One of the Red-tails appeared to be a RSHA/RTHA hybrid. It had a red tail, so that is how it was recorded. Some of the others appeared to be the Northern type.

Highlights: Adult male and female American Goshawks displayed overhead. Nice views of Red-tails, harriers and Sharp-shins. Sharpies putting on a great show while going for the decoy. One passing within 2 metres of the observer. Kettles of migrating vultures at various distances.

Birds going for the decoy: Sharp-shinned Hawks

Raptor interactions: Sharp-shinned Hawk and Sharp-shinned Hawk (aggressor listed first)

Non-raptors: Observed migrants included 490 Double-crested Cormorant, 47 American Robin, 4 Red Crossbills (many others were observed), 115 ‘blackbirds', 12 unknown songbirds

Tomorrow: Looks like clouds, maybe a little sun and probably some showers. Winds look good, but showers might shut things down. Seems like the day could go either way. Three weeks to go.
