Population check of the

Yellow-billed MagpieIn the Red Bluff Discovery Center and monitoring of birds of prey

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.

Not your average magpie Yellow-billed is a different species from the more common black billed magpie.Yellow-billed Magpie

Black-billed Magpie

Endemic SpeciesThe Yellow-billed Magpie is found only in central/northern California. Everywhere else you will find Black-billed Magpies.

Why do we have a problem now?Before 2004After 2004The main issue today is that in 2004 a huge West Nile Virus outbreak occurred.

Taking out about 50% of the population.

Magpies are very susceptible toWest Nile VirusMagpies build nests close to water where there are more mosquitoes25% of scrub jays can survive West Nile Virus, only 5% of Magpies do

The Big Ideacounting the Yellow-billed Magpie nests and the nests of other birds of prey in the 488 acre area of the Red Bluff Discovery CenterMonitor those nests for 2-3 consecutive yearsThe larger scope of this project is to get scouts and other members of our community involved in the local wildlife of our area.

Endemic means localThis is OUR bird!We need to be proud of it. We need to protect it

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.

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

SummaryThis 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 VirusI am monitoring the active nests and counting the occupants for two [2] consecutive years.

AccipiterCooper’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.

FalconsAmerican 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.

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

ButeosRed 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
