    Happy Sunday. Burrowing Owls in depend almost exclusively on prairie dogs for their homes. These owls prey on insects, lizards, and small mammals around prairie dog colonies. A species.

    I’ll resist the urge to go with a SuperB owl post and go with this fantastic dark morph Ferruginous Hawk that I found while doing raptor/corvid nest surveys yesterday.

    Superb Owl #27. Another Northern Sawwhet Owl from near home, in its typical cedar tree roost. What I love is when you find them they may give you a stare, but they NEVER flush, and often will fall back asleep in front of you.

    Spent the morning in the field being distracted by a pair of Northern Harriers, which were courting elegantly over a rolling grassland and vineyard.

    Venemous giant Sonoran centipede (Scolopendra heros) impaled on a barb to roast in the sun. Who’d do such a thing? Answer: Arizona’s year-round resident butcher bird, the notorious, adorable & blocky loggerhead shrike (Lanius ludovicianus) a songbird with the spirit of a raptor.

    Porch Goshawk ought to be a regular sight throughout the UK, making a dent in the superabundant pigeon and corvid population. Illegal persecution continues to limit their spread.
