Hi Henry, good to hear from you.
Arctic sea ice is trending lower these last few years, although it is freezing up now apparently, according to this site at least -

My garden is an ever evolving process with half of things being done mistakenly because I am still new at this, but I am living primarily on my own production now, and feel much better for it, but as you know it takes time.
The grackles (there are no crows in central Mexico, but the large Central American grackle is the same size and fills kind of the same ecological niche)
, the grackles are damaging and eating the corn of the tall native cacahuazintlies (giant native corn). They haven't eaten too much yet, so under native laws, and my organic philosophy I am not too concerned yet.
They pick at the ears when they are still moist and growing, and this kind of corn is better dried on the plant to harvest.
Last time I got them to stop by putting out a few corn tortillas for them in the morning, and they eventually lost interest altogether. I am pretty sure they are GMO corn tortillas now by what I read recently.
I also placed grocery bags over some of the ears the last few days, and that seems to work, so far. Also some of the corn plants that they have broken continue to stay green and alive, and growing their ears, even though the stem is broken and hanging straight down.
