Dear fellow flock of birders,

On my walk in the Arb today I noticed that most of the trees had lost their leaves. Exceptions include some of the Oak Trees and the Beach Trees. The ponds are frozen over but the springs like Big Spring is open at the spring itself as well as the outflow with the water temperature at 50 to 55 degrees all winter.

Por segundo año consecutivo el santuario de Cerro Pelón estará cerrado al público, decisión que fue tomada por el comisariado de nuestro ejido, sin pensar en las necesidades de la gente. Lo cual me desilusiona y me pone aún más triste. Es difícil explicar o decir una razón que justifique el porque de esta decisión, pero de verdad no la encuentro.

Dear fellow flock of birders,

When I went for my walk in the Arb this morning it was 17 degrees when I left the house but 21 degrees by the time I reached the Arb at 7:00am. Wow, what a heat wave! It was the coldest it had been in the Arb this fall but I was dressed for it.
