Gabe’s Eagle project Population check of the Yellow-billed Magpie In the Red Bluff Discovery Center and monitoring of birds of prey
2
Who is the Yellow-billed Magpie? This bird has its namesake yellow bill and bare yellow area of skin behind eye. Large white wing patches and long, wedge-shaped, iridescent greenish- black tail.
3
Not your average magpie Yellow-billed is a different species from the more common black billed magpie. Yellow-billed Magpie Black-billed Magpie
4
Endemic Species The Yellow-billed Magpie is found only in central/northern California. Everywhere else you will find Black-billed Magpies.
5
Why do we have a problem now? Before 2004 After 2004 The main issue today is that in 2004 a huge West Nile Virus outbreak occurred. Taking out about 50% of the population.
6
Magpies are very susceptible to West Nile Virus Magpies build nests close to water where there are more mosquitoes 25% of scrub jays can survive West Nile Virus, only 5% of Magpies do
7
The Big Idea counting the Yellow-billed Magpie nests and the nests of other birds of prey in the 488 acre area of the Red Bluff Discovery Center Monitor those nests for 2-3 consecutive years The larger scope of this project is to get scouts and other members of our community involved in the local wildlife of our area.
8
Endemic means local This is OUR bird! We need to be proud of it. We need to protect it
9
A young person that participates in this project will develop a relationship with our area’s wildlife. This relationship causes a long lasting effect for this person will grow to value and protect our land’s environmental resources.
10
WHY DO WE NEED TO DO THIS? Unless somebody like you care a whole awful lot, it will not get better, it will not. -Dr. Seuss The Lorax
11
Summary This project is to monitor the Yellow-billed Magpie population. The Yellow-billed Magpie population has found itself at risk in recent years due to the occurrence in 2004 of West Nile Virus I am monitoring the active nests and counting the occupants for two [2] consecutive years.
13
And since I’m there anyway…...other birds being monitored Cooper’s Hawk American Kestrel Osprey Red Tailed Hawk and Red Shoulder Hawk Great-Horned Owl
14
Accipiter Cooper’s Hawk (Accipiter cooperii). Dark-brown to slate-gray back, with a darker gray to black crown that contrasts with the lighter nape. Finely barred underparts. Undertail coverts pure white. Iris color varies from deep reddish- orange to red. Legs and cere yellow. So far I have seen none.
15
Falcons American Kestral (Falco sparverius) Smallest falcon in North America, roughly the size and shape of a Mourning Dove, (larger head). In flight, the wings are often bent and the wingtips swept back. pale when seen from below and warm, rusty brown spotted with black above, with a black band near the tip of the tail. May have found 1 nest. Still uncertain.
16
Pandions Osprey (Pandion haliaetus) The upperparts are a deep, glossy brown, while the breast and underparts are pure white. The head is white with a dark mask across the eyes. The bill is black, with a blue cere, The feet are white with black talons. A short tail and long, narrow wings with four long finger-like feathers give it a very distinctive appearance. So far I have recorded no nests
17
Buteos Red Tailed Hawk (Buteo jamaicensis) Red-tailed Hawks are large hawks very broad, rounded wings and a short, wide tail. Large females seen from a distance might fool you into thinking you’re seeing an eagle. (Until an actual eagle comes along) Most Red-tailed Hawks are rich brown above and pale below, with a streaked belly and, on the wing underside, a dark bar between shoulder and wrist. The tail is usually pale below and cinnamon-red above
18
Buteos Red Shoulder Hawk (Buteo lineatus) The Red Shouldered Hawk is Medium-sized to large hawk. Wings and tail striped black and white. Underparts barred reddish. Pale crescent near wingtips in flight
