Update on the Rosy-Finches of Sandia Crest, New Mexico. The flag is waving–
Rosy-Finch flocks are still visiting the feeders at Sandia Crest House.
This time of year we are frequently asked whether the rosy-finches will still be there when the enquirer is planning a visit to family in the Albuquerque area at Easter time. The answer differs from year to year. On average, the median date for Easter is April 7. Easter may fall anywhere between March 22 and April 25, inclusive, but, believe it or not, according to Matthew Skue at http://skuesey.googlepages.com/calculationofeaster, the most likely date is April 19.
This year, Easter falls on Sunday, March 23. Such an extremely early date means that birders will have a good chance of seeing at least one of the three species at the Sandia Crest House feeders this Easter. In 5 of the past 8 winters, flocks have persisted until March 25th or later. Stragglers were reported as late as early April in 4 of the past 5 years. The average departure date for the rosy-finch flocks is March 27th.
